Sheetz review: Cashier taking my money

I went into this sheetz on the 17th at 3am to get 25 in gas and 2 packs of cigarettes. total came out to be 43.67 i paid with card and pumped my gas. The gas pumped stopped on 20 and when I went back in to talk to my cashier she pretended not to hear me and didn't acknowledge me at all and another cashier started getting really rude with me telling me that no money will be back on my card cause I used it all I explained to her that I paid for 25 in gas and the pump stopped at 20. Once I said that she continued to be rude and threatened to call the cops on me. And I was the only person in the store the whole time the cashier who rang me up stood there and didn't say a word. So I left immediately because I no longer felt comfortable in there.they just took my money and when I called to report it to the management the next day nothing was done I just keep being told they will call me back. This sheets is full of thieves. And the next day a truck driver from my job had the same proble. I hope they do something about this because if not sheetz is gonna lose a lot of business. No one wants to go into a store and they steal your money right in front of you and then ignore you.
