Charged for someone else's petrol -refundable?

[EveSix]

Just received a notification that my account has gone overdrawn unexpectedly. Checked my account to find that I've been charged £80 for petrol at a big supermarket filling station on Sunday night.

Pay-at-the-pump was disabled so I put £10.05 of petrol in my tank and drove up to the window to pay. The attendant passed the card reader through her window, it was too dark to see the amount, but I'm pretty sure I heard her confirm my amount as I felt a bit embarrassed to put in such a tiny amount. I tapped my card, said thank you, and moved off, not realising I was being charged £80...

Have I just lost the difference, or could there be any way of getting it refunded? I feel like such an idiot, especially as the whole point of putting in only £10 was that I literally had £14 in the account.

Will your car even take £80 worth?

Have you been charged the £10.50 too? Could it be a holding fee?

Good point! To tell the truth, I've never actually filled it up (it's a fairly new-to-me banger) but I've got pretty close once at £40. I feel so stupid!

I did wonder about a holding fee, but as I've not been charged the £10.05 separately (and the £80 is a rounded figure as for a moment I thought the actual figure, albeit just a few pence different, could be outing, although I now realise that's unlikely). So in short, I don't think it's a holding fee. Two large SUVs were filling up on either side of me. I guess one of them got lucky.

Oh bugger

Dispute it with bank, explain and ask them to charge it back.

Xmas, you suggest raising the dispute with the bank and not the filling station? Can I ask why you think this may be the way to go? If anything, I'd envisaged myself possibly knocking on the attendant's booth in the morning, but perhaps I'm missing a more effective trick?
