ANYONE who has shopped in Tesco since Friday, June 11 has been urged to check their bank account and make sure they have been charged the correct amount.

The advice comes as some Tesco customers paid up to three times more for their shopping this weekend after a payment software glitch affected some card payments.

Shoppers who paid via online bank Monzo were charged twice on Friday, according to consumer website MoneySavingExpert.

However, another payment problem struck over the weekend when some shoppers tried to pay for their purchases using contactless payments, only to be told it had been declined.

They then tried to pay again, which worked, only to find that they had been charged twice – or even three times. Some customers on social media said they had to spend “endless time” on their day off talking to their bank.

Following the news that, Libby James, co-founder of www.merchantadviceservice.co.uk, commented: “This software glitch customers experienced in Tesco over the weekend could be down to a host of technical issues varying from an intermittent internet connection, to too many transactions being processed at once – it’s hard to pinpoint the problem. However, shoppers who purchased goods from Tesco over the weekend should thoroughly check their online bank transactions to ensure they have not been overcharged. For those who were affected, they should directly contact the merchant for a refund. Although technology has failed Tesco customers on this occasion, to avoid this where possible in future instances, try not be too hasty when it comes to contactless payments and wait for the transaction to be authorised, rather than tapping again to be safe.”
