The tesco pay at pump at walkden has had new displays.everytime i fill up now I get a receipt that isn't my receipt.this has happened on 7 occasions and 3 times for my wife.also one of my debit cards never works the pay at the pump.it works everywhere I shop even asda pay at the pump.the only place it doesn't work is any tesco pay at pump so have to use a different card.there is nothing wrong with the card as I say it works everywhere else and the staff don't have an answer
