I have been recieving calls from this number claiming that they are a law firm looking for someone i don't know. Everytime i called the number back i never speak to the same person and i believe this to be a scam. The messeages that he leaves, although not intended for me are somewhat menicing. I called to speak to a superviser to have my name and number removed from they list and they hung up on me.
You need to do what I did and report them to the police, FBI, FTC and the attorney general. If everyone reports it then maybe they can be found and be brought to justice.
