They promised 1000mbit and I pay for it!
I may be glad with max 230mbit despite their promises because I am not cabled and need a wireless wifi connection.

Update:

Delta, your review is as useful as a broken lamp. Local issues? The outage was in your own data center. Frustration does not solve issues...what are you going to do about it?
Contracted speed is never achieved. And I am directly connected to the modem/router via a cat6 cable. Also no internet for over 20 houses in our village (was told due to a problem in the data center) but according to Delta.nl webpage there is nothing going on..why?

It was easy peasy

Veel te traag internet.
600 mbps contract.
Beneden 204,7 download, 19,2 mbps upload.
Boven nog veel minder.
Ondanks 3 wifiboosters.

They've sent a flyer selling internet access advertising immediate availability. When looking at their website it says they've decided not to even plan to install it, let alone it being available.

Don't switch to Delta internet. They guaranteed the switch from my old internet provider. I have paid two bills now. And Delta does not accept this. The wifi is very poor, the modem keeps beating.

I've had Delta Energy and Delta Fiber services for six or seven years. So far, everything has gone as expected; my services are always available.

The internet speed is not the best and I also bought a speed booster from you. It is quite expensive for the quality offered and in some cases we have situations when we are left without internet for a short period of time.

Joined Delta in early January with a promise of fiber-cabled internet. It is now the end of March, and despite trying to call, contact, and reach them, we still have nothing in place. Stay far away! I have been on the phone with them for hours and they just forward you to the next person each time.

So, Delta keeps phoning me to get me to enter into a contract with them. I finally tell them that the reason i am not entering into a contract with them is due to the fact that i can leave NL at anytime. The assure me that i can give one month notice of cancellation and then there would be no costs. Sounds perfect so lets do it.

I wanted the 1gb line fiber but unfortunately according to the Delta representative fiber is not yet available in my area and only the ether/Lan connection is. I ask if they are certain it can reach 1000mb / 1GB p/sec as it is not fiber, they agree it will be possible, great lets do it.

After installation everything looked okay until i started monitoring the speed, it then started going down from 200mb to less then 100mb p/sec. I contacted them and they asked me over the phone to please try a few different devices, which i did and the result remained the same. The gentleman informed me that this is not good and that a technician will come to my house free of charge to fix it. Great right.

The technician shows up and plugs in his "special" laptop to show me he gets 1000mb p/sec. I show him on more than 5 different devices that i am not even getting close to 200mb p/sec. He then informs me Delta is only responsible for providing 1000mb to my/their router and what ever speed you get after that, is your problem and not theirs.

Furious and disappointed we continue to struggle with the poor speed until everything started lagging/freezing due to the poor speed. After testing the speed (on the app that the Delta technician insisted i use) i noticed i am only getting 48mb p/sec.

Not what i am paying for nor agreed to with Delta. Guess what, i receive a bill for 90 euro's for a technician to come to my house and tell me the low speed is not the problem of Delta and my issue was not resolved.

Today i contacted Delta, again, to inform them of my great dissatisfaction and i ask if i can cancel my subscription. No issues im told except it is going to cost me just a little more than 1100 euro's, yes you read that correct, just a little more than 1100 euro's. I informed the lady that this is not what was agreed to and she apologizes for her colleague who made this statement.

Now i am sitting with a subscription that i need to pay more than 1100 euro to get out off or accept that 48mb p/sec is acceptable for another 18 months or so.

I'm not sure about everyone else but to me this feels like a very big and terrible scam. I have never experienced such a pitfall in my life with all the service providers i have worked with.

We applied for fibre optic at the end of May last year. The contractor installed the fibre line 5th September. It is now the 17th March and we still have not had it completed and active. We have phoned Delta many times to sort out the issue without any luck. Between Delta and their contractor they have no clue what's going on. I have looked at Google maps for Delta head office and read through the reviews (325 of them) and they have a 1,9 rating out of 5. Some of the reviews are shocking. This company's client service is disgusting. What a useless organisation. If a company is run as badly as this you can only think that the Ceo and his management team need to go on a basic management course.

Today was the date for the Delta/ Goidion technician to install the internet and TV in my place. The time of visit agreed upon was 0800 to1159. Last minute changes without notice 1600 to 1900 hours, show up at 6pm. Gratis installation advertised but the technician wanted €370 to place a electrical socket in the closet which is outside the apartment in order to place the modem. The wifi system and [ pon] red-light continuously red is a joke. The whole company is a joke, I sent the technician home empty handed. Be careful with Giodion/ Delta technicians.
Proof and evidence and request advice, what to do now.? Both Delta/ Giodion has no reply emails.

Connectivity is currently good. There were some issues in the past which were solved promptly.

Don't speak English

Both during the signing of the contract and the installation of the fiber cable, Delta assured me there would be no issue keeping the modem in its current location (1st-floor office room). However, when the serviceman arrived to set everything up, he explained this was not possible and instead installed the modem near the fuse box. The least they could have done in this case was pull the cable to the original location (the pipes are already in the wall), but that was also not possible. Not only that, but they won’t even provide the tools for me to do it myself. All of this comes after they promised it wouldn’t be a problem—nor incur any extra charges.

Since then, I have been ignored after requesting to handle all correspondence in writing moving forward.

They continue to call during office hours despite my repeated requests to communicate via email so I can have everything documented. Every time I explain this, they claim to make a note, but the next day, I receive another call, and we go through the same conversation again.

I’m receiving barely a fifth of the advertised speed, which wouldn’t be an issue if it were at least stable. I was promised LAN but was given Wi-Fi only, which simply does not meet my professional needs.

Once you’ve signed the contract and the first payment is done, you’re essentially ignored.

Please steer clear of this ISP.

This is my last ditch effort before I file a report with the ACM.

Canceled my contract 2 months ago with customer service because they had no fiber connected in my area yet. Now I am told that because I got no confirmation of the cancellation I still have to pay for the contract.
Finally confirmed my cancellation. Only took me another month of calling, sending emails, images of my call history and cancellation forms. Still got charged a week after they finally confirmed my cancellation and resent their package to me. Will have to wait 2 weeks to get my money back and go out of my way to return their package.

I tried to call them to install internet in my house and the lady from the phone refused to speak english with me.

She wants only to speak Dutch. I think in 2024 when half of the country are foregins without Dutch they should hire somebody who knows english language or who is not so racist to refuse to speak it.
