Comet

Thief and liar!!!!!!

I have a big problem with comet. I bought tv with extended warranty. After 1.5 year in november 2012 it broke down so i called comet. they took my tv and said that it should takes a few days and they call me back. I havent had any info so i called them. They said that they was closing down and send my tv to warranty group. So i called warranty group and women said to me that they havent got my tv, that comet still have it. I called comet this week and they said that they lost my tv and they have to make investigation what had happened. I dont know what to do. I paid for it £800 and I want it back!!!maybe somebody has some clue how to solve this problem?
