Travis a 5 star salesman
Travis was so friendly and approachable. Went in for an upgrade on my phone and ended up walking away with a Phone and iPad for less than what I was paying before just because he was committed to getting me a good deal. These staff are trained well and he is a super salesman.

Brandon and Luke were outstanding. First class service from the management in store who were able to solve my issue first time with no hassle.
I had an issue on my account due to fraud that was immediately spotted and resolved by both gents. I feel extremely relieved to have come to this shop to get this sorted.

My go to Store!
I had a brilliant experience in the Belfast Castle Lane store, I was helped by Patrick with something I thought was an O2 issue and later realised was my phone being broke.
Patrick was still able to help me fix my issue and was extremely informative about the upgrading process setting me up with a new device.

Brandon and Patrick
I visited the O2 store on Castle Lane, Belfast, regarding an issue with my data usage following an upgrade to a new phone and tariff. Brandon and Patrick were both extremely helpful, polite, and friendly throughout my visit.
They were committed to resolving my issue and took the time to investigate it thoroughly. Although the issue could not be resolved during my visit, this was outside of their control and through no fault of their own. They raised a ticket with the technical team on my behalf and provided a solution that allowed me to continue using my phone as normal, avoiding both loss of service and additional charges until the issue could be resolved.
They also gave me clear advice on the next steps and explained the plan moving forward. I really appreciated their patience and excellent customer service.
Thanks
Kerri
