Number blocked. Problem solved.

They called this morning, asked my name and then wanted the last 4 digits of my SSN.  When I told them I don't give that info out without them first confirming who they are and the reason for their call, they said, "Fine, we'll just take your number out of the system - good luck to you."  Not sure if that last bit was to try and scare me or what, but I don't confirm my SSN - not even the last 4 digits - for anyone.  If they can't tell me why they're calling, then they'll get no info from me.  I get scam calls all the time asking for the person that previously had my phone number.  

I received a threatening call from this number demanding payment for a 1995 credit card judgement, according to the caller. Funny thing since I migrated to the USA in 2007 and only have two credit cards which I keep current. To be on the safe side I called both credit card banks and was told that must be a prank call. How to I block this caller from future calls? Thank you in advance for your help.

Put a call blocker on your phone.if u know the number u can block it right away. If not block it after they call again
