Been on the phone to CS and TS all day.
Finally convinced them that, no restarting my computer wasn't going to solve the problem, and managed to get an Engineer visiting tommorow "around 1-5" to "Check the connection"
Just gotta hope that he actually listens and replaces modem, i may have to show him this forum
From what i've heard though, most people seem to have got the modem when they requested it, so i have high hopes mine will be replaced.
Fingers crossed
Might be worth adding, i specifically requested a 250 , to which the reply was "NTL now only distribute the 250, so that's what you will get" , if that's worth anything to anyone.
