I was in a similar situation once, where i eliminated everything on my side, including router and computers. (Even though it was working fine before and all of a sudden i got really slow speeds without changing anything) Virgin also claimed no fault at their end, which left the modem itself. Got it replaced and everything was back to normal, so that may be something to look into.

I also agree with the suggestion to use the newsgroup instead of calling, get better and quicker help that way.
