Customer service is non-existent. As others have previously reported, pathetic and totally inadequate replies are 'cut and pasted' from a menu that the agents, all who appear to be based on the Indian sub-continent, have access to. They do not actually understand the nature of the complaint or problem. Five different agents have all replied with similar banal comments apologising, but not actually addressing the problem. I'm having to complain to Groupon head office in the hope of getting someone with some understanding of customer service to address my issue. Can't wait to see the 'canned reply' to this review. No, let me guess... blah blah blah, Support@Groupon
