I too had terrible problems with ViginMedia which they ignored for many weeks. I got two letters, in June and August both saying I would get a response in 10 or maybe 15 days. When I tried to cancel I was told they would charge me a couple of hundred pounds for the priviledge of doing so. I'm still waiting for a response from them as their service is lousy compared to NTL which they took over. I keep losing connections especially when trying to use my phone as well. How they come out as PC Advisers best bet I have no idea.
