I just noticed that my local gas station GetGo (affiliated with super market Giant Eagle) is coding for Service Station instead of gas. I spent ~$5000 there last month and just realized I'm only getting 1% instead of 5% cash back with the old blue card. Am I SOL? It has always coded as gas for Visa/MC/Discover. I know that certain stations (sams club, costco) don't code as gas but this is a legitimate gas station sometimes miles away from their grocery store sister. Thanks for any advice. I'm nervous to contact AMEX since it's a high amount of bonus spend on 5x and I did buy gift cards most of the time.
