Yesterday, because I have to wait 4 days to get my broadband connection repaired, I filled in the feedback form at
http://www.cableforum.co.uk/board/ntl.php
I actually got a response and within 24 hours as well. They will, it seems, "credit" me for loss of service. I have to admit that I didn't think I would get a response, let alone an acceptable one, so well done NTL.
Now I wait to see if they will actually credit me for loss of service.
It's just a shame that NTL have gone down hill so much recently. A few years ago, I had a couple of cases of getting an engineer within 24 to fix faults, not any more! I've even had one support person refuse to talk to me because I was not at home to help diagnose the fault!
