770-300-XXXX

They called me and left me a message and then when you called the number back it says the number has been disconnected

I have received 5 calls from this number at work and they will not ID them selves. I have told them that this was a place of business and for them not to call back, at first it was a woman calling now it’s a man, a***n they will not ID themselves.  They have also called me on my cell phone, who they must have obtained illegally from a third party.I need more information, so that I can report the company to the office of the Attorney General.
