I HATE NTL - we have all 3 services with them and when we move I will never, ever use them again (can't be bothered to change right now as it's a bit of a hassle). Their Customer Service absolutely stinks! Everything is OK if all is working fine but if not then don't bother asking them for help! And yes the TV does keep stalling (my Mum has Sky and had it for years and never has this problem).
Earlier this year our desktop pc went bang, we got it repaired and needed to reinstall the NTL broadband software (which we couldn't find). Asked them to send a new one out - it took them 7 weeks to send out a CD!!!! After endless phone calls (some of which were getting irate) - they said they had a backlog and there was nothing they could to about it! Tough basically! Oh and then 3 CDs turned up the same day!
As a 3 service user was told I was entitled to a discount which I was told had been applied to our account. I rang up to query something about 3 months later and was told I was eligible for a discount - I mentioned I'd already been told this and thought I had the discount. I was told "oh no, you have a discount for 2 services but not for the 3rd one - I'll add it now"???? So I asked if the discount could be backdated if I'd been eligible for about 9 months and it should have been activated on my account - the answer "er no"!.
I called to ask about the £30 for 3 services that they advertise (as we use all 3 now and pay a lot more!!!). Was told it was for 'new customers only'! (sounds like that bank advert) So I asked if there were any other discounts we could get, the answer was 'yes we can apply 'said' discount'. When I asked why I hadn't received this one sooner the answer was "we have 1000s of customers, we can't just go applying discounts to every customer as we don't have the time, if you ASK for the discount we are obliged to give it to you, but only if you ask" WTF?
Sorry to rant, but I hope you get the picture of how utterly crap they are. Please don't touch them with a bargepole. The only saving grace I can think of is that now they have merged with Virgin perhaps things are improving but I've seen no evidence of it so far...... They are always on Watchdog for being crap!
