Ive heard of this happening a few times with folks on the so called "freedom" package.. I really dont know why people should be tired down with a contract with a service they are apparently not happy with.. Even more so if you have used their services for over 12 months in all..
I to up and downgrade my packages with ntl every few months just to suit my budget and needs, they wouldnt dare tie me to another 12 month contract, so why they would do it with freedom customers I really dont know...
I hope all goes well.. Warning though, make sure you have a tranfer code from Tiscali, I hear they are pretty impossible to move away from also, and their packages look crap anyways
