Worst customer service ever, refuse to help me. Continually tell me it's a vpn and I don't use a vpn, then tried to say I use an iPhone from Europe then changed the story again to say my phone has been compromised. I weekly scan my phone for unusual activity and nothing is found, the system error is on their end but continue to blame me. I suggest you use a different fuel app, when it does work it will change prices from purchase to deduction from account. Several times I've noticed this.

Hi Matt, we'd love to look into this again for you. You should be able to open the Mudflap app if you're located in the US, so we want to investigate. Please call us at 1-888-885-3835 and request to speak to a manager so we can help. And to ensure you get the advertised discount, lock in a price for a full 24 hours by creating a fuel code.

Truck Route does not work very well, Some times it give you the best fueling stops and sometimes it simply shows you ALL the stops along your route, Not much help. Also the GPS software needs improvement The look is horrible and the notifications block the view. They also need more stops. In some areas they have NO Coverage. It is a good alternative to fee based fuel cards.

Hi Billy, thanks for the feedback. Pro tip: when you enter your route you can select the "Cost Saver" or "Time Saver" option to avoid seeing all stops. We'd love to hear more about your experience with navigation. It's new and your suggestions could really help us improve. Call us anytime at 1-888-885-3835 to share more. Hope to hear from you soon!

waited on the phone for 32 minutes trying to verify my account. looked up all of their small charges on 3 different cards, took pictures of myself and my driver's license and after all of that, they say the verification will take up to 72 hours. I'm sitting at the fuel pump now. absolutely ridiculous. been using this app for years without issue. i'll be looking at other discount options.
