I GOT A BOGUS CALL FROM THIS NUMBER, SAYING THAT I SUPPOSEDLY WON A FREE PHONE.  WHEN I TOLD HIM I WAS NOT INTERESTED, HE CALLED ME 8 MORE TIMES, SAYING OBSENE WORDS AND MAKING FUN OF ME, HE INSULTED ME SEVERAL TIMES.  HE USED INAPPROPRIATE AND RUDE WORDS.  
I TRIED TO TALK TO HIS SUPERVISOR, BUT HE JUST CONNECTED ME TO SOME OTHER GUY, WHO ALSO INSULTED ME.
PLEASE, DO NOT ANSWER ANY CALLS FROM THIS NUMBER.
