if you need to complain about tiscali contact CISAS, but first write to tiscali recorded letter if they dont reply or sort out your problem get in touch with cisas.
i have been waiting since the 14 december for my line to be taken over by tiscali every time i ring customer support they always tell you to ring an 0845 number then they tell you to ring another number seems to me that this is a money making scheme for tiscali as you dont get anyware when you ring these numbers. so today i got in touch with ofcom who took all the details and gave me this number for CISAS020752038. i shall be ringing them as soon as i can cofirm that tiscali have recieved the recorded letter.will keep you posted.
