They called my business cell phone 2 times alone today. No message was left. Not sure how they even got my number, its a cell phone and its listed under my business name and not my personal name.

I received a phone call from this number and it said unknown caller

tells you to call 800-824-6191 for false debt

Called, hung up without leaving a message.  Usually a sign that they aren't for real.  So much for the do not call list.

Called my cell phone twice today.  Didn't leave any message.
