Useless piece of crap. Customer service... is there one? Can't get through to them via phone, text or email. After 4 attempts, I finally got their card, the explanation being it had been sent to my former address. Wha...? Huh? I've lived at this address for over 35 years, well before GB existed. Emails either go unanswered or are answered with the screwiest replies weeks later. App is a bad joke. Pop-ups out the kazoo, proving NOTHING is free. Really off-the-wall gas station locations when I plug in my Memphis, TN zip code. Kansas City, KS and Oak Park, IL... really? I uninstalled the app from my phone and tried to unsubscribe from their emails, but couldn't find a link to do that within their emails or on their website, so for what it may be worth, I unsubscribed via GMail's link, hopefully sedning GB's emails straight to Spam. I'd like to be able to send it straight to Trash or better, have the option of sending GB emails straight to Hell. Gas "Buddy" my $#*!!
