Firstly,

to the CF Orior.
As you've already discovered there's a whole wealth of information here that may, or may not, help you on the path to true NTL enlightenment.
Secondly, I didn't read Orior's post as an attack against
all NTL staff. I thought that it was aimed at the people (or, more likely, the processes) who had perpetrated the horrible crimes described in it. I also took it to be more tongue in cheek than some others may have read it.
I can understand why people would be upset to read it, especially today when the NTL service staff seem to be coming in for more that their fair share of stick, but it's just a tongue in cheek rant - much the same as many of us post here about other companies faults.
I don't imagine that the OP ever intended any offence, I'm sure he/she (?) recognises as much as I do, the great asset that the NTL bods represent to this forum - and of course that there are some good NTL CS staff (who know what they're talking about, care about their customers, and go out of their way to help them wherever possible).
