I'm with TT now.
No problem with service.
But got a bit hacked off by them increasing my Broadband cost.
Then they go fishing for new customers offering free broadband.
I complained. They then sent a letter offering 50% discount on my current broadband package.
So far on two occasions I have phoned to get the package they have had problems with the system, just before this all blew up. Surprise.
I think they have a few more disgruntled customers who know how to hack into the system!
