Apalling customer service. I ended my contract (Ive been a customer for decades), as i emigrated. Paid to leave my contract, waited the 30 days notice, they shut my O2 app access down and told me to wait for a final bill. I told them if there was any difference, i would have to organise money as my UK bank account would no longer be active. No issue they said, we will refund to another UK account for you. Heard nothing, got an email saying i dont owe anything, so i rang to check everything was closed etc. Im told O2 owe me money, I said great, youll have to repay it to another card as the previous payment card is no longer active, person went to check with supervisor. 25 minutes calling from abroad and am then told, they will refund to my card that is no longer active and then i need to ring my bank and sort out getting the money back from them! Im not even sure you can make a transaction to a card that is no longer active???? They cant refund me any other way apparently. The person had a terrible command of English and couldnt even pronounce my simple English name correctly!! So, O2 have my money. Thieves!!!
