Comet

Television not repaired after 8 weeks!

My television stopped working nearly 8 weeks ago, at the time of purchase we took out an extended warranty, so it was still covered. 3 engineers came and went and couldn't fix it. It has now been in the workshop for over two weeks. I have heard nothing from Comet and have phoned several times on their premium rate number for updates. Each time I am told that it is due to go in for repair "tomorrow".. it seems that tomorrow never comes! I am without a television 8 weeks down the line, so I'm wondering if there was much point taking out extended warranty in the first place?
