'A Software glitch' is a bit nebulous to say the least. Who's software ASDA's/Petrol Pump supplier/Card Co? You have no way of knowing- Would you care? As your 'Contract to Supply' is with ASDA laurie53 is correct as first stop. But attack from both ends is the best strategy- so challenge the Card Co too- let both sort it.
Agree. Tackle both ends at the same time. I'm sure ASDA will want it sorting out, they seem a decent and honest company.
I'm surprised they don't have software checks that forbid the use of the same credit card for the same sum of money within X minutes. It seems common on toll roads in France for example (where they won't even allow the same credit card to be used for payment withing X minutes, no matter what the amount is). Seems such a simple check on an automated system.
Was it for the same amount.And the same time.I once got charged for petrol and as I use diesel I challenged the charge.I have a[ Asda fuel card]so did not notice until I received my monthly bill.It took me almost a year to get a refund.
