Valero Orange, CT review: Unauthorized charges for gas

I was in your location on 09/15 around 7:30 pm purchased gas inside the store with the gentleman named Mooney. I told him I wanted to fill up my tank and all he said was he was going to open the pump for me. Never specified an amount that was going to be held. I only purchased 15.00 worth of gas and he has my account on hold for 50.00 . First he tried to chay100.00 and I stopped him. I need my money back ! Because of this my whole account is on hold!
