I bought a ** gift card to postmates and attempted to use it last night.For some reason it would not verify neither of my debit cards, and even though the order came to *.** they would not bring anything without verifying my debit card. which I've never had a problem using anywhere else. So for ** hours now I've been emailing them and asking them for either a refund or the help me get something out of the $** out of mine they have. They have not responded to a single email but still find time to send me promotional things advertising a ton of things I couldn't buy if I wanted.I have a sick girlfriend and dog I am taking care of, and am in town in a hotel room with no car here. It is ** degrees and nothing is close. I need either my money back or something we can eat.. Can you help resolve this. My name is Brad Harnice and I am in Louisville KY
