We came in to upgrade my husbands iPhone. The 3 boys in store were extremely helpful and gave us a great deal which included a Lenovo tablet. They have also given us great advice to upgrade to the family plan when my contract is up in Feb 2027. In addition to this they supported us to to get virgin media for our new house. They also supported my husband to switch over his apps and photos to his new phone.

My mum and I visited the Castle street store in Belfast. My father recently passed away and we wanted to inform O2 regarding his account. We were dealt with by staff with the utmost understanding and respect and we would like to express our gratitude to the staff for their help and support. Emma in particular was incredibly kind and helpful.

Outstanding customer service from Gary
I have had issues with 02 for 2 and a half years as a customer, 2 visits in store with member of staff Gary and all of these issues have been eliminated.
Gary could not have been more helpful, friendly and supportive to my situation. He resolved the wrongful debt put on to my account, and has saved me from potentially loosing my home due to this debt. I could have cried with relief leaving the store today after speaking with Gary, the effort he has put into my case to resolve has been immense. Even writing this review I simply cannot put into words JUST how thankful I am for Gary and the help he has given me. I sincerely hope that this review is taken into consideration and he is recognised fully for his outstanding customer care and service. Get this man a pay raise ASAP - seriously, I mean that.
Thank you again Gary ❤️

The brilliant Travis
Well where do I start, on what was a grey dull day in Belfast, was certainly made much brighter by the service provided by a young gentleman by the name of Travis. Travis welcomed me with metaphorical open arms, with a cheeky smile that could sell ice to the Eskimos. Travis helped me sort my issue with ease and answered every possible question I had. Travis also reassured me that 02 were very much an eco friendly company which helped me come to the realisation that I came to the right decision in sticking with 02. Travis couldn’t have been any better and I believe you have a real gem on your hands. Overall great experience.

I am very happy with O2
I am very happy with O2, and this is down to the staff in their shops. I had a problem with my phone and Debbie (Cornmarket branch) sorted it . The welcome at the door, and the referral to Debbie was quick, and welcoming. I would recommend O2, the after service has to be one of the best on the high street.

Your recommendation means a great deal to us, and we'll be sure to share your kind words with Debbie and the rest of the Cornmarket team.

First Class Service
The service I received was first class. I had stopped in with a question of curiousity on how the O2 switch worked as far as transferring all the data from one to the other and a lady named Emma helped me out and I was able to upgrade to a new phone and get a free Samsung tablet for less money than I was paying. Thank you Emma.

Brilliant experience
Gary and Travis were absolutely amazing. After a nightmare over the phone trying to figure out why my daughter’s fone wasn’t calling out I went into the shop as a last ditch effort to sort it. Gary got into my account and with him and Travis looking at it they found their was a block ont the account from a fraud case in January. Travis called them to get it removed and got me a new iPad for cheap that I’ll give to her as an early wee bday present. Brilliant professional service done with a smile! Will. Be. Back.
