I'm posting this on behalf of a mate of mine who's has a big problem with his BB connection.
On Wednesday morning at around 1am his BB connection stopped working, when it stopped working he said sod it and went to bed thinking it would be on in the morning, he got up at 3am to see if it was working, it had downloaded 1 email since 1am the one he'd been trying to get at 1am.
On Wednesday morning he phoned tech support who tried all sorts of tests but to no avail, they then passed him onto level 2 tech support who told him it wasn't his Cable modem, they booked an engineer to call on Monday

Now this was Wednesday morning and they could only get an engineer for Monday
He made another phone call to Glasgow for more info on a engineer, the lady advised him to phone at the end of the day to see if there had been any cancellations, he phoned back only to be told that the systems were down.
He phoned Glasgow again on Thursday morning, a guy called Steve who was one of the most jobsworth people you could ever wish to come across in a call centre, all he did was go through the motions telling him that nothing more could be done at this time his attitude stunk.
That afternoon he phoned tech support again to see if there had been any change, they told him that there had been a system failure in the area and he would be back on within a few hours, now bear this in mind his neighbours who are on NTL their systems were working fine

The Indian guy told him to unplug all the wires from the back of the modem and leave it + he was told to turn the PC off and leave it that would cure it. No Change
Later that day he phoned C/S in Manchester and spoke to a cracking girl called Danielle who was 100% genuine (unlike Steve in Glasgow.) She put a complaint for him, she also told him to write a letter of complaint to NTL she gave him all the addresses to write to.
Now my mate has worked with computers since 1988, he was the main programmer for CPL in Chesterfield, he's built no end of machines for people, he's built no end of websites for people, he's got a cracking reputation round Mansfield for his PC skills, to get his machine working he's done a IP renew, deleted the TCP/IP and reinstalled the protocol.
I have his Mac address here if any of you kind NTL bods can give him a dig out.
