hi gez and
to cable forum.
The pin is something you will need to get from CS. This site does have some ntl staff visiting it, and helping out if they can, but as it is not part of ntl, cannot help you directly. It sounds as if you were being given the run around. If the modem is now on line, I would expect CS to be able to see it. Perhaps try the broadband support number or faults? Certainly don't expect a call back, it frequently doesn't happen.
