Cant get Tiscali off me back and its hurting!! What a fine bunch of .......they are

[Appuleius]

I was told when I signed up for TalkTalk (in Carphone Warehouse Meadowhall Sheffield on 12/2/1910) that EVERYTHING would be done for me to changover from Tiscali, including cancelling my account with Tiscali,and MAC code etc.
WELL the BB and Phone service went live on 27th January, this was fine and exactly as promised, and I am satisfied with BB and Phone package.
BUT Tiscali are pestering me to pay there account up to 31/3/'10
I phoned Tiscali on 28th January to ascertain my account had been cancelled, I was passed from department to department and spoke to mainly ladies with Indian accents, then one lady said please phone 0871 222 3311 our cancellation department, I did
then they confirmed my account was NOT cancelled, and to send proof I was with TT, I photocopied page 3 of the TT Welcome book and posted it recorded delivery (past experience has taught me when dealing with Tiscali NEVER do anything which you cant prove later!) I was told to post it to P.O.Box 14505 Birmingham I did exactly that with all details a/c No etc. Incidentally the phone call messing about with the 0871 number cost me £4-60 despite I am with TT for all time calls!
I received a letter from TalkTalk (NO mention of Tiscali on the letter at all just my Tiscali Cust Code) saying We have notified BT to remove our BB service from your landline on 31st March !!
Getting jumpy I phoned TT to make sure I would not loose all services from them on 31st March, they assured me I would not, and said these letters were sent out from a Mr Nigel Pearson by error!
Today 22nd March another Indian lady phoned me demanding I pay them up to 31st March, I politely refused, saying they had NO chance whatsever, and put me in court if you want to! she would not let me speak to a superviser, but told me post evidence to 11 Evesham Street London W114AR giving evidence of being with TT fro 27th January, I told her I had done this before on THEIR request with the address they had supplied me with, she said Birmingham was not the correct place!
I wont go on any more (I could)
YES I KNOW THIS IS PERHAPS NOT THE CORRECT PLACE TO COMPLAIN BUT PLEASE, PLEASE, CAN ANYBODY HELP ME I UNDERSTAND TT OWN TISCALI.
IM NOT HOLDING MY BREATH
