Well, I'm too late to vote on the poll, but I would have said 50/50 - I've only been with NTL for a couple of months, and have got digital TV, phone and BB.
On the whole, the service has been pretty reliable ...just a couple of occaisions when the BB has gone a bit haywire, but in all fairness, these have not always been NTL's fault (ie, the French undersea transatlantic cable that got damaged last month, etc...)
The only gripe is that it took them an extremely long time to install everything - I mean the delay between ordering (and paying!) and the engineer visiting to hook everything up. What made it even worse is that they told me they would arrive on one day, but turned up a week later. When I phoned their CS, they swore that they had always said they would come on the following week. However, the day before they finally came, I received a letter welcoming me to NTL, which said my Go-Live date was the previous week!
...they also 'forgot' to switch over my phone from BT, which required me having to phone and moan at 'em.
...plus I always have to wait at least 20 mins to get through to anybody. Bit annoying.
Oh, and I'm in Wiltshire, and don't work for NTL
