Virtually NO Customer Service I have purchased a large number of Groupon deals. Some of the products are good and a bargain. Some are marginal but what you'd expect for the price. However, I purchased a carpeting cleaning deal to be fulfilled by a company called National Dusters. When I called to schedule an appointment, they told me they did not service my area. I promptly notified Groupon by responding to an email I received from them. When my credit card bill arrived, I discovered that Groupon had billed me for the deal AND National Dusters had billed me an amount that was greater than the deal price. Since the Groupon website did not provide any obvious information as how to contact Customer Service, I went to my credit card company. They were unable to resolve the issue. I went back to Groupon and tried several things that were supposed to get me to customer service. The best I could do, was to get into a loop that sent me non-nonsensical emails. I emailed National Dusters and thus far have not received a response. Before this, I would have given Groupon a good rating, but this experience has resulted in two stars which is probably more than they deserve.
