Well When I had VM at my place in Bham they came at 5:55pm (slot is 1-6).
In Leicester the slot was 1-6 but they rang me at 10am saying they wanted to come..which was fair enough I just wanted the job done.
Only problem I had was...I wanted the BT Master socket to be left alone so my ADSL would still function..however they ripped all my telephone wiring apart and put new sockets in upstairs and downstairs...So the only problem I have now is if I want to switch back to BT i'll need an engineer to come round

.
Not to sure about the adsl charge, i'm with SKY LLU, So I just rang them yesterday and asked them to cancel my broadband. My Bt Line is already in the process of being canceled.
I hope montfort does not get FTTC for a long time now lol...after making the change to VM, I am still pretty sure that a lot of the area does not know they can get VM cable services as no leaflets have been posted. I only found out due to this site
