Yes, that is what I think too. And since my wife swiped the card and then cancelled the transaction, the $75.00 should have gone immediately to zero. Some posters do not seem to understand the nature of my post. NO PURCHASE OCCURRED.
She did not even remove the nozzle from the pump.
The hold went on when the card was swiped, and most likely the hold was canceled as soon as the transaction was. Holds will take a few days to be removed by the bank after they are canceled, that’s just how it works.
Actually, the fact that “no purchase occurred” probably made things worse for you. There is a difference between canceled holds and settled holds. A settled hold is when the business places a hold for, say, $75 on your card and then completes the charge for $45. That’s immediate. But canceled holds ALWAYS take longer to drop off. If your wife had purchased $0.01 of gas the hold would have dropped off much faster, but since it was just a canceled hold you will need to wait.
