After writing to complain O2 contacted me to inform me that they had messed up my account and I was owed £90 refund. This was over a month ago and still no money has been received. I’ve given my debit card details four times and last Friday I was informed that a BACS transfer would be made. It would take 5 working days to show in my bank account. Well nothing has appeared. I phoned O2 was informed managers don’t speak with customers and there is nothing further they can do. So it looks like I’m going to have to go to the small claims Court. Disgusting useless service. AVOID at all costs
