Avoid at all costs
I paid for a £10 top up on O2. Followed instructions on both the phone numbers given but told repeatedly the code not valid. Ontopup helpline had no service when I phoned to comment. The next day I had a call, was told that no refund could be given after the 16 digit code had been issued, even if it didn’t work ! I was told that the technical department would look into my claim and respond within 24-48 hours. That was 3 days ago, I have not been contacted.
