Back in march 2017 someone used my bank details and get contact from o2. When I noticed that they withdraw £9.99 from my account I called o2 to find out. we understood that it is been a fraud. So they said they stopped the contract. They refund £9.99 then some day they withdraw £9.99 again. I called in they said there has been a mistake and they gone sort it. I contact the bank bank and they they also said they will contact to o2 to make sure it is sorted. I thought it was okay. O2 did not send me any letter for opening or closing the account. But last year I noticed that On my credit report it shows I didn’t pay for five months and owe them £55. I emailed there credit referral team, fraud team but no reply. Just to clear my name on 20th January 2022 I called o2 to pay that £55. The girl who answer the call struggled to find the account then finally she said she find it and took the payment but nothing changed. I call o2 every day they say they can’t find account or anything with my name and address.Plus they couldn’t even find out what happened to that £55 I paid. This can not happen even in any corner shop. Now I’m selling my flat. It’s nearly completed and I find the house, our offer accepted. It’s on solicitors hands but because of this problem no bank wants to give me Morgege. Soon We will be homeless with three children.
