Customers of supermarket giant Tesco are urged to check their bank statements after payments were being taken months after shopping.
The issue has affected payments made in 300 of its Tesco Express stores, of which there are branches on Chester's Delamere and Pepper Streets and on Upton's Weston Grove.
Some shoppers have reported that it took up to three months for their payments to be processed.
The retailer explained its card payments system did not fully process the transactions made on credit and debit cards since November – resulting in a delay in money exiting accounts.
According to BirminghamLive , some complained they had been charged for multiple shops all at once - meaning hundreds of pounds could potentially be leaving your account.
Tesco says it's proactively contacted "as many affected customers as possible" about the issue.
Financial experts are urging Tesco shoppers to check statements immediately if they have shopped at an Express store over the past three months.
Julie told MoneySavingExpert.com : "I was both shocked and horrified to find out Tesco had taken three months to put through contactless transactions.
"These said transactions range from November 2017 through to January 2018.
"Nothing was indicated on my online statements as to pending payments and they've now presented me with these bills after nearly three months.
"I run a tight budget and they have now told me that there are nine transactions that were not processed correctly and that they would take them all out now."
Adam, who received a letter about the issue from Tesco, added: "Taking nearly two months to send a letter out is a bit too long.
"I called them to say that I can't pay it all at once as this will take me overdrawn, only to be told that the money will come out of my bank in the next few days."
Since we've published this story a number of users have let us know they've also been affected, including Emma who said: "£129 taken out of [my account] - now got no money."
A Tesco spokesperson said: “As soon as we identified this issue, we contacted as many affected customers as possible and have now processed all incomplete transactions.
"The issue has now been resolved and we are sorry for any inconvenience this may have caused.”
