Just called and I'm on the National wide do not call list and also have an unlisted number! I listed to the voice mail and it was asking about medical insurance need in an automated recorded voice ,also asked me to press9 to be removed but this is a no no coming from Private investigation background, because there is some apps out there that will attach and listen in and log your where abouts
This number continues to call and when you call back it immediately has a busy signal. They are contacting me on my cell phone and there should be no reason for this. Not sure who they are, but they are calling too much.
