Gubhub used to be great to order from and in the past they were always responsive to any concerns--NOT anymore.
Been trying for several days to get them to reverse fraudulent charges which were generated from their system. When I contacted them there were 4 fraudulent charges. Not only did they not correct those charges (and have not done so to date) but they allowed TWO additional charges from OTHER clients to be charged to my credit card. DO NOT let them store your credit card info (and you have to make sure you uncheck the store credit card info box) and DON'T use a credit card on their site either. Personally I am taking it a step further and not doing business with them again-EVER.
