Same thing, we usually get called by this number on weekends.  I never pick up "Unknown" or "Unavailable".

This number just called me and said I owe Chase $1500.  When I said I'm not sure what you're talking about please call back, he starts being rude and says just take care of your balance with a debit card right now.  I hung up and tried calling the number back to see if it was a prank call, it kept coming busy.  I'd say they're crooks and trying to make people pay up for random stuff.

they called and asked for somebody. and if we were that somebody press 1. i waited and they hung up on me. couldnt understand...

Wanted to confirm I am who he hoped by last 4 of my social - I asked why? Wouldn't tell - I asked for last 4 of his social - stalemate. Still calls every 5 to 30 days - I still do not answer and reject if I happen to have phone in hand.

I'm a night shift worker and just got to sleep in my bed and this number called me.  When I answered there was noone on the other line so I hung up and they called again just a minute later and still noone was on the other end.  VERY ANNOYING!!!!  I don't owe money to anyone!!!
