Thanks to all. Met my new routine:
unknown number calls
don't answer
check web sites like this to see if scam likely
block forever
"Your call is not important to us"
called at 5:10pm on 11/07/16 and on 10/19/16. no message left. called id states PBCASHPRO - Matampras, PA. call is blocked now but no doubt will pop up again under another name and/or number.
