Worked for NTL for several years but don't generally advertise the fact now. Some folk like to offload their frustrations on you. And they're right of course because the NTL support is still rubbish. Maybe once the Virgin brand gets a hold on them things should improve but this doesn't help people pulling their hair out now!. I've had a couple of problems with the BT broadband but generally get straight through to someone in their call centre in India. Give them their due, they normally have an answer or solution fairly quickly. Don't like the yahoo toolbar though, too distracting. What've you got?
If I had the choice, I'd have BT. I only take the NTL since I have cable anyway and I was too busy or too lazy to change at the time.
