This number will call asking for the person whose name the telephone is registered under and if you ask them question they will swear at you.  The person seems to be of Sri Lankan and his name he claims is Rankan.  He maybe targetting elderly's and scamming them money or something.  He calls with his caller ID.

I received a call just now claiming he's from the united way and his name was Shan.  Hung up as soon as I questioned him on the number display.
