A bill for £10,000 on a credit card would be a concern for most people - but imagine if that spending was not by the cardholder, but by fraudsters in a single day.
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.
