Not Worth the Trouble When it Doesn't Work – Upside: Cash Back - Gas & Food Review

I've tried to figure this out for months. App worked fine for quite some time. All of a sudden I was receiving no cash back and getting emails saying such. I did everything customer service asked me to do to make it work. Still nothing. The issue was, it took up to 2 weeks to find out I didnt earn cash back. Driving a larger car, i would have filled up a couple times in that time. So when it came to it I had to search my purchase history at my bank and submit proof of purchase. Sure I could do that, but nothing was ever done from their end to fix the problem. Use at your own risk.
