Fraud was committed by using my Tesco Card without my consent. It may have been one of my children but they won't admit it. I am paperless and I hardly used the card so I didn't get month statements therefore I didn't see any transactions. After nearly 6 months and £6,600 debt later, on a routine on-line statement check, I saw my debt to my horror. I immediately stopped the card. I believe that Tesco had a duty of care to warn me of unusual activity, (all payments to the same gaming company, some days up to £400). They deny this and refuse to help let alone accept some or even part of the responsibility. £6600 of transactions to the same gaming company. One phone call to check this was ok was all that was needed. To add insult to injury, they continue to charge me interest at 19%. Is there anything that I can do? Guy.
