I have a landline and 2mb broadband from NTL (btw very happy with the service), in 2 different accounts.
Today i tried to make a phone call, but my line was dead. To cut a long story short, i was told from customer services that on 25/10/2005 i have asked my landline to be moved in another address
The problem is that neither i called them for that, neither i am moving a house. I asked them for the address that it was asked to be moved, and it was somewhere in York (i live in Portsmouth). I canceld that action and i will have to wait till Monday to get connected again
I am sure that someone is playing games against me, because something like that happened again to me 2 months ago. I received a bill from "3" (mobile network) saying that i have a contract with them and i owed them 20 pounds

I called them, saying i never made a contract with them, and they refused to give me the store details in order to go there and check the details. This account was canceled so i could not make any further action.
But now, i think the same guy has done that with NTL . I am suspicious about one man, but without proof i cannot do anything.
I want to write a letter to NTL in order to ask more info if they have, do you guys think they have any more info? Do they keep records for the calls the receive? Maybe they have the phone number that guy used to call them.
Where i should send this letter? To the address noted in the back of my bill?
I know, so many questions, but as you may imagine i am quite worried and angry.

I have a password on my NTL account, i am sure no one might know it, and i think the cc representative didn't asked for a password before he/she took this action. I know that because most of the times i have called them the just ask for name and 1st line of address.
Please help!!
