Well i cant grumble,TW have been ok with me, had 3 house moves and no charges, only been with out service 3 times since they started there 512 service many moons ago...Well i do contract to them as well as contracting to BT to and Also NTL and Cable & Wireless.
There will all ways be hickups when upgrading,just like when upgrading a pc,sometimes smooth sometimes hassle.
In general i think the Broadband service in Uk is very good and at a fair price..
My 10 meg is ok,Some days i've had issues with email,but downloading and surfing,playing games been fine. down load between .800 and 1.3 and at a saving of £15 pm over my 4 meg service(£50pm).
