Hi Paul, I too cannot understand why reconnection would take so long in this instance.
As this is a previously connected line Ntl should be able to reconnect the line in office, there must be some technical reason why they can't do this or some complete incompatent has followed the wrong reconnection process!
If there is a lifeline requirement for the phone they should be pulling out the stops to get you connected, this doesn't appear to be the case here!
Oh yes and welcome!
