wont leave message

from who seemed to be indian said they were microsoft asked us to type in prefetch in run box on computer said that our firewall was down, didn't proceed/ does anyone know who they are?

Unknow caller`s.

This person claims that they are a Lawyer and that he would take me to court and have me served and arrested and lose my job. They state that they had tried to get ahold of me via email...it was probably in the junk mail if they did and I never received the information. I was never received any information in the mail. They want x amount of money today or else they will send it to the courts.

Person said me would not give me any information about the loan he said i took out. I ask for him to send me a fax of the information and he told he no he can not send me this until I pay him.

Never answered. The caller never left any message.
