So .....

NTL have no guarantee that matches BT ..... so what ...

NTL will use best endeavours to rectify a fault.
BT will use best endeavours to rectify a fault.

If the NTL fault is an extended fault they do on occasion offer compensation, if you ask for it.
If the BT fault is an extended fault they do offer compensation, if you ask for it.

BT have been going a lot longer than NTL, and the guarantee quoted earlier is strictly for phone lines only. NTL have a more diverse product range, and still have some ground to catch up on, but I will say again, they are getting better.

The recent problem I had with the phone line bore that out too. Not everyone who has experienced a fault will automatically clamber on the compensation bandwagon, most are just happy that the fault has been rectified.

I'm not saying that NTL are wonderful in all aspects of their business, the CS experience really needs attention, but they are getting better.
