No response to query

Hi I have logged a request last year and still haven't had any response to my query #***1. I again through email logged a response on the 12th of January and to date nothing. Groupon do send me messages asking me how I feel about their response to my request. How can i feel you haven't done anything for months about it!!! I used to be an avid groupon customer but lately I must admit that I have been disillusioned by their lack of support. You can try to phone their call centre and being told you are the next person to be assisted , but after hold on for 1/2 hour you just give up. GROUPON YOU NEED TO GET YOUR ACT TOGETHER, SEEING THE MANY COMPLAINTS I'M OBVIOUSLY NOT THE ONLY PERSON EXPERIENCING BAD AFTER SALE SERVICE!!
