A driver says she has been left with no money after £99 was blocked out of her account when she filled up her car with petrol at Asda.
Iona told Mirror Money how £129.02 was pending in her account - despite only buying £30.02 of petrol - thanks to pre-authorisation checks that are used at supermarket fuel forecourts.
The idea of the pre-authorisation check is that it blocks out money from your account - £99 at Asda, but at other supermarkets it is £120 - so the store knows you can afford to pay for your fuel.
