Hi again
Just wanted to give you all an update on the above problems.
It's now nearly a week later, and the internet connection is still on!

This wouldn't be so bad if they had decided to stop billing us for this service, but I bet that'll be rolling in to my Mum's any time soon
Someone on here very kindly emailed me directly and said they'd look in to this for me, and that it would be sorted out. Sadly I can't seem to find their contact details so can't email them again for more advice and an update.
If someone "on the inside" has made some enquiries on my behalf, how long would it normally take for things to be sorted?
At the moment, it looks like I'm going to have to go down the on-hold for 50 minutes route again, unless anyone has a better idea? Someone suggested I should try writing/emailing certain directors at NTL - realistically, who would be the best people to approach with this one?
Again, very best wishes
