threatens me to get money

Received call at work. 8:15am call is from Spokane Washington state. They must start early there. I returned a call to the number, reached an answering machine. They are a marketing company that conducts surveys for other companies. This is the 3rd or 4th time I have received a call, they have never left a message.

Call to Alberta, Canada Dec. 22nd, 2010

Indian spoken man left a message on my voice mail stating that he was an officer of the law, and I was in deep legal mess, If I did not call him back I would be in big trouble. A thought came to mind one I could not understand him clearly, and he was very threatnening, which is unprofessional.

caller id showed- California call--our answer-machine pickedup....they leftn no message!

Je reçois plusieurs fois par jour des appels venant de ce numéro. En général 2-3 sonneries. Mais en répondant il n'y a personne au bout du fil. Que puis-je faire pour faire cesser ce harcelement?

I have one 1 of 3 gifts from signing up to win a car between the last 12 to 18 months, please call as this will be the only attempt to contact me.

Called twice. Tried to call back. The message on the other end... We're sorry, due to telephone company facility trouble, your call cannot be completed at this time. Will you try your call again later.
