I shopped at Casey's for years before installing the app. I made a purchase and they not only didn't give me credits I should have received for the purchase, they took half the credits I already had. Multiple attempts to contact the store manager and Casey's website got no response from either. The loss of the credits wasn't a big deal. The lack of response severely annoyed me. It's a good thing Casey's doesn't need my money, because, I've never spent another cent there.
