Oh, the trust thing is spot on! I'm driving to the shooting range, filling up with gas through Upside, already with $40 cashback, and then the app says "transaction declined." I'm standing at the pump like a loser, empty, 60 miles to the range. Furious, I found best upside phone number, called, and they fixed it in 8 minutes, plus they charged me an extra $10 for the inconvenience. Now I can fill up without any worries and even buy coffee with the money I saved. Are you also fighting for reliability, or are you fighting for maximum cashback?
