Staff attitudes,at Amersham.

I bought a phone today,but told it's policy not to set up new phones,having bought one a month ago,for my wife,the assistant did set it up.Todays episode,put my back up,only to be told by the assistant,that I was talking to her,in an angry manner.This assistant,to my mind,had no intention of helping me,I am 80 yrs old,not computer savvy,and had to elicit help,to remove and insert a SIM card.May I suggest giving staff instruction on helping OAPs.We served our country, couldn't your staff,SERVE us,after all,they will be old sometime.

Appalling customer service and no mobile data available in France

I have been a customer for around 15 years. Service was previously ok and I recommended Tesco mobile in the past. Never again. What has happened? Have Tesco mobile outsourced customer services?
FAILURES OF SERVICE:
- Mobile data no longer working in France (for whole of 2 week period (it did work fine over the previous 4 years)
- Tesco mobile can give no explanation and no resolution to the problem (O2 worked fine for a a family member not on a Tesco mobile contract who was with me)
- None of their trouble shooting options worked
- Tesco mobile state they cannot assure me it won't keep happening each time I am in France (which is quite often)
- So 'home from home' service no longer available
- Tesco mobile sent me text messages and left voicemail messages during this period despite knowing I had no mobile data to receive these.
- No longer an option to leave a personal greeting when a phone call is received but you are unable to answer phone at that time.
- Poor and inconsistent advice every time contact with customer services made.
- 'Live' chat can take over an hour to respond.
- No attempt to address concerns and put right - just a 'computer says no' approach. Customers not valued.

Be warned and shop elsewhere - I now have to change my provider to get what should be a basic standard service.

The worst customer service I've ever experienced

Quite awful. I don't think I've ever dealt with such terrible customer service. They mis-sold my 89 year old Mum a complicated phone that she struggles to use, without advising that she could port her existing number from BT or that she could put her existing BT SIM into an unlocked phone. The phone has terrible signal at her house and she was in a state because she couldn't keep in touch with me (her daughter). Since then we've been trying to return the phone and cancel the contract. Countless visits, emails and phone calls later, we are no further forward! We've been given different information by everyone we've spoken to and I still haven't been able to register my power of attorney with them. Avoid at all costs!

Useless Tesco call centre

I rang Tesco mobile on 7th April(Tuesday) to swap from pay monthly, to pay as you go. Was told it was going to take 24 hours. No problem I thought. It's now Friday 10th April and still it hasn't been done. I have rang up everyday and was told it'll take 48 hours then phoned up again to be told it's going to be another 24 hour and I'm going to get compensation. Bloody incompetent. Update 11th April, phone number still not working. Keep getting told different things every time I ring, like today. Update 13th April.... Phone number still not working as they promised, they are now telling me I need a new SIM card, however I did ask them last week if I needed a new one and got told no, the one you have will work fine.

AVOID

For the last 3 days I have been trying to transfer my old phone number from a Tesco mobile contract to my new Tesco contract, everyone that I have spoken to has barely spoken a word of English. I have been told 3 times that it will be complete in 24 hours, they also tried to charge me £322.00 While trying to check to see if it had changed I noticed a bill on my account of £47.00 when I paid the remainder of my old contract which was £63.00 and I also paid the start of my new contract which is £17.50, I still have no answers as to why or where this bill has came from and no apology either, I have been with Tesco mobile for 13 years and I have never had any issues, the last 3 days have been a nightmare and my issue still isn’t resolved, avoid at all costs

The Reviews below are Shocking

The Reviews below are Shocking? Here is another review added to this Useless Company! I ordered a Tesco Sim about a week ago and they took my money but never sent the item out. They never gave me any Tracking number to track the item, I can't even contact customer service because "contact us" is not working on their Tescomobile website...Stay away from this useless Tesco site.

I would give minus one if i could

I would give minus one if i could. Tesco really sold out. I used to associate Tesco as a UK company with decent customer service. Every time i try and contact them either by online chat or phone, I end up getting angry because they literally talk rubbish. A combination of strong accents, very poor English and a seemingly complete inability to understand the issue I'm explaining means I end up ending the conversation none the wiser. They don't even understand how their own systems and products work.

Updated app asks me to re-enter all of my details each time I top up. The least they could remember is my email,home address, etc. also I stay within my bundle usage but sometimes the remaining balance is different. I tried to speak to customer services but they couldn't explain it.

What a complete and utter farce this…

What a complete and utter farce this Telephone service is. A simple £10 pound a month sim card, where there's NO physical way for me to pay. Ring up and complain and get abuse from Indian call workers. App never works, website say's I'm not a customer, etc etc. And I have spent over an hour talking to some bloody idiot, in Indian, just to get a PAC code so I can leave. Only been a customer for 2 months. What a complete and utter shambles.

I had a bad experience at Tesco Mobile…

I had a bad experience at Tesco Mobile store At Bellshill Tesco..the Young lad was helpful at first, but dfter providing me with phone deals booklet I had requested things changed, I had a brief glance at the booklet and was about to ask a question regards deal offers,when he cautioned me and instructed me to move around to the other side of the desk,as I was " in his space " there was no signage to say staff only,and didn't understand what he meant,I politely asked what he meant,and he again quoted, that I was in his space..other customers waiting looked up to see what was happening, I asked again what he meant and was accused of escalating the situation..I was deeply upset by his attitude and asked to speak to the Manager,he then went to fetch him and I stood out of the Tesco Mobile area, until the Manager arrived,I felt really embarrassed as the other waiting customers were looking over at the situation..I was made to feel that I had committed a crime or done something wrong,..I was approached politely by the Manager who asked to explain the situation, which I did, and assured him that I in no way, raised my voice or made any threats to the member of staff to justify any offence to the staff, but told him that I personally felt deeply offended, and reminded him that I was a customer with rights as well..He did apologise, and I told him that I would no longer be interested in dealing with Tesco Mobile deals, and would take my business elsewhere as I not impressed and left with a sickening feeling after this horrible experience..I am typing this review 3 hours after the incident and still feeling rattled by this..I will certainly not be doing business with Tesco Mobile in future, if this is the standard of staff attitude to a prospective customer, and I will now take my business elsewhere from another provider. 🤔

A SIM card was ordered and paid for but not delivered

A SIM card was ordered on my behalf a week ago. I was keen to stay with Tesco mobile because I wanted to continue using the same tel. number. Unfortunately a SIM card has not arrived by 30/03/26 and I have a very strong feeling that it actually will never arrive. Tesco should have the decency to inform me of this problem at least and if necessary admit that they are unable to supply a new SIM card

Shocking customer service

Tesco mobile - I ordered a phone passed all checks and their payment system couldn’t take the payment for the deposit 3 times this happened with different bank cards ! They have now credit checked me twice, I still have no phone even though they admitted it was their system problem, I have now spent 2 hours on the phone to them getting passed around to different people - absolute joke of a company I’ve never experienced anything like it.

Staff don't seem knowledgeable anymore

1) Two weeks ago I was told by staff that my previous PAYG would no longer work. To continue without contract I would need a new SIM. I called on the Friday (at the time number was still working so passed security with team) and was told I needed the new SIM by Monday so one would be ordered. I expected it to take a few days but after one week it did not arrive and I was unable to access my number or get through any banking sites in meantime. I called from another line and asked if the SIM was definitely ordered (hoping they could order replacement) as I had not received it and someone in house ordered wirh another network (after my call) which came within two working days. The staff on the phone could not confirm and I was told I couldn't pass security because I needed text. How can I get text if I'm waiting for new SIM and have no connection. The agent then said that he was not sure what the previous agent told me and could not go into my account to check as I could not pass security without the text. I kept telling him that I wasn't able to do this so he then tried to ask something else which I didnt know as it was related to a balance and I couldnt check. He then said I did not need the new SIM (even though week before the lady said that SIM would stop working and I would need new one before my line would work) and the issue wasn't the SIM but a problem in my area. There was a problem in my area as other people were having issues but this was intermittent and they could still see a signal. However when trying to explain this to this staff and the fact that it was likely because I needed the SIM which had not arrived he was adamant that it was just due to issue in area. He refused to accept it could be anything else so I was told that I needed to wait for the issue to be resolved in my area now so cannot access banking until this is resolved. He did not seem at all concerned that I was without a number and made an arrogant assumption that he was right and I did not know what I was talking about. He was not rude exactly but very dismissive and someone who makes assumption rathering than gathering information to get to the root cause 2) I was owed a cheque which finally arrived after two weeks (processed by that inital agent) but they have spelt my name wrong. It's not just one letter. I can tell it is meant for me but almost like they tried to guess the spelling. Absolutely ridiculous for a professional phone company who would have my name on the system, however I also spelt it twice over phone at two separate times and the agent seemed to pronounce it correctly at the time. There are mistakes with both first and last name so I cannot take to my bank as I am confident that they will not accept. So now I will have to spend another morning calling them up if I can even get through security without my number working. Assuming this agent does listen, I will now have to wait even longer to get the correct cheque.

I used to love being a Tesco mobile customer. In the past (about 2-3 years ago) I found it very easy to speak to the staff. It was always so easy raising a query and the staff seemed very knowledgeable with good customer service skills. I have not had to reach out much from that time until now. I am not sure what has changed recently but just based on numerous interactions in last month, I have been disappointed with the staff I have spoken to. Once I do have my SIM issue sorted, I am seriously considering leaving due to staff seeming incompetent and having to explain a simple issue multiple times until they understand what I am referring to.

Disgusting Tesco Mobile .

I have had limited and no signal with Tesco Mobile for the last 3 /4 months. I have complained numerous times but just keep getting told that there is a phone mast not working near me and that it will be sorted out. Most of the time I cannot make or receive phone calls and I don't have a landline. I'm mid contract and have been told that it will cost me over £100 to leave my contract. Tesco Mobile are an utter disgrace.
