StuG, if you send me the mac address of your cable modem and your postcode i will have a look and see what the problems are here- as you have an engineer booked already this will just be to see why there were problems with the request going through in the first place.
All of the modems that are used on the ntl network can easily support 1.5mb from the original 3com CMX's to the current Ambit, so there would be no need to swap modems as a result of the speed upgrade. And Zeph, you are correct- it is only the PACE set top boxes that need to be swapped for Samsung boxes to receive the speed upgrades, stand alone modems are perfectly suitable for the upgrade.

EDIT: oh and both the faults department and engineers do work saturdays- the network maintainence teams are working 24/7 as well
