o2 have been deducting various payments from my bank account, but were however unable to identify why these payments were being deducted, and repeatedly asked me to provide a GED code from bank in order for them to identify the payments. My bank explained that they do not have a GED code however o2 kept insisting that I had to provide this. o2 tried to tell me that the payments that were deducted were for my pay as you go phone and I had used my card to top up. I do not not have a pay as you go phone. My bank identified that o2 had tried to take 4 payments from my account over the course of 5 days. In the end, after hours of back and fourth conversations, I had to cancel my debit card and log a case of fraud with my bank as o2 provided me with no help at all. The level of customer service provided from o2 was appalling, impersonal, and at times quite difficult. So much so that I am considering leaving my o2 monthly contract and moving to another provider.
