Gulf Oil Petrol Over — charge mistake
I visited a Gulf Oil petrol station today and selected the "maximum £80" petrol option, as I knew I needed around £45 to fill my tank and the next lowest option was £40. I have just checked my bank account to see that I have been charged the full £80, as opposed to the £45 I actually filled my car with. I assume this is a mistake as I should only have been charged for what I actually withdrew. The max limit is surely just to stop me going over, not to actually confirm the amount I would pay.
I have a receipt of my transaction and would greatly appreciate assistance in getting this resolved, and only paying for what I actually used.
