Gary at O2 in Belfast Corn Market was a breath of fresh air from the usual customer service reps that you have to deal with. Gary was able to change over my old Sim onto a New one which I purchased at the store. He explained and confirmed what needed done without any fuss whilst dealing with queries from his colleagues who to put it politely where not as knowledgeable as he was in dealing with technical issues. He is a credit to the O2 establishment- Well done.
