Automated message asking me to confirm my place of residence. not sure who this is or what they want. I just hung up the phone.

I got the same call today. I think it's a scam

This number has called me repeatedly and just recently called my place of business.  They do not answer once I pick up the phone and when the call is transfered to me at my job, they sit silently on the phone then hang up.  They actually told our receptionist they were calling me to "verify my address for a legal matter".  I do not have any legal matters that I am aware of nor do I think if this was from a legit lawyers office that they would ask a receptionist my personal information.   The messages they leave for my home are simply distorted and sound like a bunch of people acting crazy in the background. My phone company advised I block their number. I believe this is a scam and am very upset regarding the harassing calls to my job. Any suggestions?
