I put £20 in my car on Friday at Asda pay at pump. I know it says something about authorizing £99, however ever since then the £99 has been taken out my bank (it's in pending transactions but the money has still been taken and I'm unable to use it) as well as the separate £20 transaction. This has never happened before and I'm getting concerned now. I don't use this very often so not sure how exactly it works but I really need that £99 now to pay bills and I can't have it just sat pending. Anyone know more about this or what I can do? Is it worth contacting bank?
