Hi guys, I know this thread seems quitr old, but as I am in the process of changing my ISP and phone from TT to BT, I thought I would put my 2 pennyworth in. I was originally with Tiscali, I was very happy with the service, I had unlimited downloads and it was reasonably fast. Then Tiscali were bought out by TT. I received an e-mail advising of changes to the terms and conditions and asking if I wanted to sign up for a new 18 month contract. I declined, despite being called by them to sign up. Speeds now are not great and I decided to go back to BT, who I was with before Tiscali and as BT seem to have learned that they have to offer better deals now they do not have a monopoly. I sent an e-mail to TT requesting a MAC code, 2 days later they called me and advised that as I was on LLU, they didn't use MAC codes, (even though, there is a LLU MAC code.) The caller asked why I wanted to change and I told them I was not happy with the speed and 40gb, got the usual blurb about let us see if we can come to some arrangment. Stopped him right there. BT advised that there was no problem over the MAC code and gave me a good deal. I am waiting for a final bill from TT and do not expect to have to pay anything but the 1 months BB line rental etc. God help them if they want more. As they say, watch this space.
