Another added: “Tesco annoyingly made duplicate transactions for my shopping yesterday. Now I need to wait for more than a month for the refund.”

“@Tesco just been charged twice for an in store transaction that apparently was not successful. So frustrated,” a third continued.

Another stated: “@Tesco I was in store today and there was a problem with the contactless payment the staff member asked me to use the chip and pin as the transaction didn’t work – just checked my bank and I’ve been charged twice.”
