They sold me a defective TV set and ignoring my return request.

I bought a TV online and got it delivered exactly 2 weeks ago but when I put it on, it had a huge black block that obscured most of the screen. I immediately requested for a return and provided all the information they asked for including photos.The only update I got last Monday was that the issue has been escalated to head office. The agent Ruqaiyah has been ignoring my emails since then. I checked my ticket and noticed that it was closed. I guess I have been ********** by Game. Very disappointed.
