I have my number registered in do not call register service of MTNL from the year 2007 but still a single person named Puneet from ICICI Prudential keeps calling me from different Noida numbers like 0120-6776300. After informing numerous time (10-15 times) that i am registered in do not disturb still this person keeps calling me and he enjoys my discomfort when i hear his sales pitch.
Is there any way to teach a lesson to this kind of persons?
