Still no response re: ipad

I bought a new iPad 2 from groupon in November. It doesn't work. I have send groupon about 5 emails a day since then. The only rely I have gotten is 'please advise if you have lodged a return' but I did that months ago!!! This still continue to send promotional emails so that are happy to take money from people and they have time to do this apparently! They don't have time to help me return my non-functioning iPad. NEVER AGAIN
