Horrible customer service

I bought a groupon voucher about a month ago. The groupon codes were not working on the site of which I wanted to purchase from.<br> <br> after that I tried contacting groupon about the code not working and logged a query with them Request #***0. In which case the guy gave me the incorrect contact info for the company I wish to buy from.<br> I notified this person that the info is incorrect and he sent me the \Correct"contact info. WHICH WAS ALSO INCORRECT. I told him that it's still incorrect and have not yet received a response back it's been over a month since my groupon purchase and the coupon expires on the 8th of this month!! I have tried contacting them with a new query but no response. <br> <br> I find this unacceptable! """
