I report calls like this to the FCC's Do Not Call Registry as my numbers are listed. Anyone doing marketing or sales calls are required by Law to run their call list against the FCC's Do Not Call Registry list and remove and never call those numbers registered with the FCC DNC list. Every violation can warrant a fine for failure to follow the law.
Then I also go onto the FBI website and file a complaint with the FBI Fraud Division as people like this are committing fraud.
Hopefully some day they will be tracked down, dragged into court, and prosecuted.
Get this call many times - no msg. I do not answer calls f rom numbers I do not know. I assume if someone really needs to talk to me, they will leave msg on machine telling me what they want.
