This number just means someone on Facebook called you using the free Bobsled.com service

What did you do to get rid of this call? I am getting calls from same number and it disturbs em big time.

416-841-5154 ran over my dresser, bad person, beware of this human.

yes it is a message from face book  caller

I have been called by this number with someone claiming they work for Microsoft and that I have security problems with my computer.  The man, who had an Indian accent, told us they provided a service to monitor our security remotely and that for $250 they would provide that service.  It appears that they are not really Microsoft representatives but they have essentially defrauded me of the $250.  
What if anything can I do about that?
