How's that going to help if you're not home.

Get calls from this number, almost daily, sometimes twice a day. Monday-Friday. THEY never leave a message.

Got a call just now; they identified themselves as "Secure ID," which is the name of the legitimate RSA 2-factor authentication gear (software and key dongles). He was pitching "identity protection" specifically for people over 50 - clearly trying to scam seniors, ignoring the do-not-call list. Pond scum just above child molesters, IMHO. Caller identified himself as "Fred" - maybe I should have invited Fred to come by for a friendly chat with a feeble old man... SFPD (above) and I could perhaps gently persuade him to engage in a new line of work. ;-)

I keep getting calls from this number more than 2 times a day and they don't leave a message!  I'm going to block them.

If you call them back there is an option (2) that will supposedly put you on their Do Not Call list.
