On TalkTalk with international phone and saving ?40 a month over my Bulldog service.
Phone connected in 4 weeks, broadband 7 weeks (a week longer than told)
Support could not tell me if the line was enabled or not after go live date and before actual connection of broadband.
With my two previous broadband suppliers I had set up problems as well so I expect this as normal. I judge it based on being in over a month.

Since it has been up I have had no problems. Getting 2Mb consistent and that's fine by me.

Based on my experience I have no problems with TalkTalk and if I had to decide again I would still go with TalkTalk.
