I have had ntl's 512 Mb BB since August and it has been a disaster - awful web site connection at busy times, but good download speed once connected. Now the service is so slow is is effectively useless. I've had engineers out and long chats with their technical people to make sure the problem wasn't at my end. ntl then admitted last week that contention ratio on my bit of the network was peaking at 350:1, 7 times the nominal 50:1, but that they were not planning to spend the money to fix it. Any ideas on what I should do now (apart from go back to BT)?
