Paypal, eBay’s online payment system, has refunded some of its UK customers after a technical glitch saw them charged twice for transactions.

“Due to a technical error on Monday 24 and Tuesday 25 July, some PayPal account holders experienced duplicate credit or debit transactions on their accounts,” said a statement from the firm.

“PayPal has already refunded duplicate debits from customers accounts and corrected accounts for transactions that were credited twice to bank accounts.”

The company also said that it would not debit the accounts of users that had been over-credited, rather than over-debited.

As reported by The Register, the move echoes a similar incident last year.
