FYI Just because you are on do not call list means nothing. You have to report the call an even then odds are very small you will get an answer to your complaint. Per their own website the FTC has only handled a few hundred do no call complaints.
Not a known # by me. People need to understand Do Not Call list is Does Not Work list. Don't answer! Don't call back! BLOCK CALL. Scammers just electronically change numbers. If messages left its IRS SCAM WARNING or FREE CRUISE crap.
