I received a series of 5 calls... two that showed up on my Caller ID as "Private Number" then immediately followed by three calls from this number (754) 300-0169.  I finally able to answer the third call and a guy says that a note was left on his doorstep saying to call my number.  I replied that he must have the wrong number.  Then he was joined by a woman's voice and they both indicated that a note was left on their doorstep saying "Call me, b**ch" and they asked me if I was a lawyer.  I'm not a lawyer, have no idea who these people are or how they got my cell phone number.  This is unnerving to say the least.  After the call unended, I did a quick search and saw that the number is associated with a VoIP service.
