Two pensioners have told BBC Radio 4's Money Box that they each had around £10,000 worth of fraudulent transactions put on their Barclaycards. In both cases the criminals managed to dupe the card issuer's telephone banking system and procedures to spot suspicious transactions. Barclaycard insists it has an excellent track record in fighting fraud. It says the transactions have now been removed from the two customers' accounts.

Bob, from Exeter, was shocked when he discovered a fraudster had racked up £9,200 on his credit card in a single day. The criminal had made 16 successful individual transactions of between £500 and £750, all at Apple stores in Bristol. The purchases were believed to be for iPhones and other electronic goods. Bob says he cannot believe the transactions were allowed to go through. he says. Bob became even more concerned as he became aware of how his card and Pin number had been obtained two weeks earlier to make those 16 purchases in Bristol.
