Wow I had a problem with BT broadband and was told by the BT help desk it was a problem with vista, the next day i got a call from someone saying they were from microsoft technical and that BT had said there was a problem with windows and demanded a hundred and eighty quid, I got a phone number to ring to authenticate it, phoned the police and passed on the number on, they phoned back and said they had checked the phone number on the police computer and there had been thousands of complaints worldwide connected with this particular telephone number.
