How can we stop these marketing calls from bajaj fin serv.. Every day they call 5 to 6 times per day.
There are so many companies who take the customers for granted. The common customer is so busy with his daily work that he does not have time to go around and run behind the legal bodies / police. Our system is such that anyone can harrass anyone and get away without any issues. Let us take the example of bajaj finserv. This company keeps calling you every day at least 5-6 times for marketing. They have a robot in place which dials all the people and plays a recorded audio. The poor customers might be in the middle of anything serious / may be in a crisis, but these corporates just do not care. They will call you brazenly and try to market their company. Our country does not have a system in place that people can stay peacefully and are not being harrassed by these corporates. Can we stop these calls from reaching our phones. I am not sure who has given them the right to call our phones and harrass us.
