U have a point there. I agree with you. But, at Janpath or Sarojninagar or for that matter anywhere, they are not going to come to your house or follow you wherever you go, unlike telecallers who persistently keep calling even if you request them not to do so or decline their offer. They will get back to you from someother number or by someother name. They have ur telephone number and mind you they can call you anytime of the day without even bothering to consider where ur or what ur doing.
