I have just phoned Ntl Cs, spoke to a very pleasant Scottish lady, she did not know when the speed upgrades come into being, she checked and came back to inform me that they had no idea other than "the end of March" and advised me to wait until I received mail notification before ringing again.
When I mentioned the 8th of March she wanted to know how I had come by this info, she said the little bird I had been speaking to was better informed then her.
