This is in fact a telemarketing SCAM

you can help by calling the FCC as described in the post to which I am replying.  It takes some time to navigate through the appropriate menu for unwanted telephone calls and faxes, but once you get to that menu option, select the number "0" to report the complaint.  I had to listen to the FCC recording several times to understand that part.

Also, it seems the Federal Trade Commission (FTC) is more likely to process your complaint as their jurisdiction is more complete in this case.  In order to report the complaint to the FTC, call


877-382-4357

OR go to

www.ftc.gov

And select ....
Consumer Protection

Then
