Martin Lewis has sent out a warning to customers who have a bank account with Barclaycard.
The founder of The Money Saving Expert sent out the message during his namesake ITV show this week.
In a section called 'time for a quickie... or three' he addressed all current or former Barclaycard customers, Lancs Live reports.
Martin Lewis said: "This is the warning for Barclaycard current or ex customers.
"Do not bin its post. It's sending out payments for incorrect interest and fee refunds for some pre 2019 repayment plans.
"The average payment is £70 - some may get up to 300 quid. It's paid by cheque, by transfer or to the card.
"So don't throw your post away if you're a Barclaycard former customer or current customer."
