Same here and I'm fuming.

It's gone midnight, and I've been online for 1 hour, for the first time today, just like someone 'Switched' me back on. When the kids go back to school I will be able to browse until about 4:pm, and that's it again, until near midnight. Weekends are also out.
I've been with Telewest for 12 years, and had their Broadband from day one. My problem also started last September/October. I have a Manager who is keeping me updated, and he's phoning me again on January 4th. First I was told it would be resolved by Christmas; then Mid-January, and when I spoke to him a few days ago it was "The first quarter year"
I was also told it's not a fault, it's an issue? What's that all about?! I'm sick of hearing about UBR's, Upstreams and goodness knows what else; I don't understand it anyway.
I've made up my mind. It's bye bye Blueyonder for me
They've merged with NTL, and bitten off more than they can chew, and that stupid advert for more customers is still being shown on the tele.
They can take their Broadband, Phone and Tele package and shove it .....
I best leave it there .... .....
