Megan is correct, when you use a debit card at the pump the pump the bank holds 75 dollars so it know you won't over draw on your account. This is your bank holding the money and they put it back in your account after the transaction is processed. To avoid the $75 you can pay with a credit card or pay inside the store
I have had this happen at other gas station's. Takes it a few days but it will fix it self by returning your money back. Could take 7-10 days depending on the bank.
