No product/no response

Ordered a product on 30 March. On 2 April I was informed it had been shipped. When I called a few weeks later I was told it had been destroyed in a fire - noone bothered to tell me. I e-mailed Groupon on 16 April and received a response that it would be resent in 7 - 10 working days. Having not received it I e-mailed on 13 May, 17 may, 19 May and 25 May. They promise to respond within 2 days, then mail to say they are overloaded (not really surprised as they are useless) and then just ignore the issue completely. They used to be good but have obviously got too big. I will not be using them again if this is how they treat their customers.
