Monzo customers face technical issues paying for goods at some Tesco branches due to a problem with the supermarket's payments system.

Some Tesco branches had erected signs asking customers not to use Monzo cards after months of complaints from customers who said it appeared they were being charged twice.

A Tesco spokesman said that Monzo customers are allowed to continue using their cards in branches.

The problems began in July when users of the online bank started complaining about problems at Tesco self service tills.

One Monzo customer posted on Twitter earlier this month: “Been double charged by Monzo at Tesco for the second time in two days and third time in a few months. Sort it out please Monzo.”

Another customer wrote “Hey Monzo how come I just got double billed Tesco and why is the app saying I have to wait a month for my money back. It should never have gone!!!”
