Terrible Service!

I am extremely upset as well as frustrated with Groupon. I purchased a rug from them in December 2015 and when I received it, it had a huge stain on it. I sent an email in the next two days and received a response that I should send them a picture of the rug. After numerous emails to them, I received no response back yet my complaint was never dealt with. I tried calling them later in December but their customer care lines were so busy that I wasted all of my airtime while on hold. Today I finally had the opportunity to speak to them directly and the consultant on the other end was extremely discourteous when he informed me that there was no more stock of the rug and that I should send another email in order to facilitate the process of reimbur*****t. I am truly upset at the way I have been treated by a company through whom I regularly order products.
