Ratings and reviews

The app used to work great, but for the past two weeks I can’t use it. Every time I try to get a fuel code, it asks for a one-time bank security code, which is good for safety. But after verification, it gives me an invalid fuel code that doesn’t work at the pump or cashier. The code appears on a black background and seems shorter than before. My bank also shows two identical pending transactions. Please fix this bug.

It gives you a code and then it just says invalid at the pump when you try to use it. Sucks you in with promise of cheap fuel and then doesn't give it to you. It was a waste of time and money because I ended up paying more by waiting and going to that station vs another cheaper one. 50 cents off seemed to good to be true and it was. Fool me once.

Used exclusively in April for fuel. Earned Gold status for May, only, it wasn't awarded, customer service isn't only lacking its non existent. I've been going back and forth with emails since May 1st, its May 27th. Other apps offer real rewards and honor points earned. Other apps also have real, and live, customer support. For sanity and frustration sake... use a better app.
