These people are obviously calling from the state of kerala in India.  They have been harassing us for the last 3 years and wont stop calling even though we have told them we don't want their services, have hung up on them, and have threatened them, etc.  It is completely irrational and only those who know the stupidity of people from kerala will understand this irrational behaviour.

They just keep calling. They are supposed to leave a message.

Called me this morning. Not responding to my greetings. Hung up while I kept saying hello.
