Unknown call because I refuse to answer obvious scammers and unknown phone numbers.  I guess it's no skin off the scammers noses, because they just keep programming their Robo-caller to tell whatever they want you to know.  Secret is, although there is NO secret...DO NOT ANSWER PHONE CALLS UNLESS YOU RECOGNIZE THE PHONE NUMBER CALLING.  And once they stop ringing, immediately BLOCK their worthless scamming double-wide backsides.  If you can't kill 'em, BLOCK 'em.

2nd call - using different phone number to avoid blocking.
