Take your money
Do not go to this gas station and use a credit card as payment. Not only will they stop the pump short of your request, they will argue about it and make you feel like you agreed to the lesser amount only to later check your account online to find the higher amount. I called right after I figured this out which was from work exactly one hour later. I did call the station to rectify this only to be given a run around as I wanted the difference to be refunded on to my card.
I will going there later personally to collect my refund. I will never be going to this gas station again.
