Cenex

I filled up my tank on November 30th at 6:45 PM (it costed $15.53) and when I got home, I saw a Pending transaction of $76 to the same place (a Cenex that is also a Cubby's convenience store). I'm lead to believe that the Cenex station here in Blair is holding $76 that I absolutely did not spend there. It's 7:30 the next day (December 1st) and that $76 has not come back to the available balance in my VISA. It is quite ridiculous that they can hold that much money for that long and make me very anxious to see it back in my available balance.
