No response from Groupon

I have ordered a product on 8 June that was to be delivered within 2 weeks. We are going for 3 and I have queried the status of the delivery. I have not even received any reply or response on the enquiry, except a mail to rate the service received on the request - What service????? (Ticket #***4) and (Ticket #***9) This is not how I am used to know groupon service. I have ordered lots of items and products and never received this pathetic service. Is Groupon going out of business, as it seems most likely with this service??????
