My dad is on TalkTalk and has had no problems with them.
My girlfriends Grandad is on TalkTalk, had one problem with them on the line, but the bigger problem was dealing with their call centre.
Don't know if BT are offshore call centres or not, but that was one of the reasons I chose Plusnet instead.
