Decent app but need better discounts and quit charging card fees.

I love the MudFlap app except the new feature that's lock you out and have to call in to get number at pump because I was a snow bird last winter and drove a gas vehicle all winter so when I was ready to drove 3000 miles home , I was shut off and every fill I had to call in that was a pain . I think for security it's ok to shut me off but if I call in once then you should be able to turn it back on with our me having to wait a week or two until it automatically turns back on . Very inconvenient

I wish your stops all had enter your number at the pump. The only draw back is standing in line waiting while someone is taking 30 minutes to decide what lottery ticket to buy.

Not directly a Mudflap issue, but it's time-consuming to have to occupy a pump so you have a pump number, walk across the lot to the service desk, give them the pump number & Mudflap code, walk back out to the truck, fuel up, then again walk back in to sign a ticket & get a receipt. Only once have I been at a stop (on I-44 west of STL) where I was able to enter the code at the pump, fuel up, get a receipt, & go.

I've had excellent service and credibility using the mud flap app. The only problem has been the being card being refused at Large I thought reputable dealers. More often than not places like Loves, and Flying j, would not honor the card or their prepaid limitations were so stringent it wasn't worth the time to fuel. These instances mainly occurred freeway routes in Pennsylvania Ohio and Indiana. Other than a few situations response to the card has been good. Savings realized have been excellent.
