Intellipaat — Continuous calls when declared not interested

My name is Alekhya. I just enquired regarding a course for one time.That was the mistake I made. I keep on getting calls.I told them I was interested in the beginning but due to my personal reasons I was not interested and said not to call.But that did not stop.They called me atleast 5 times a day for a week.If I won't pickup the call they just keep on calling.After talking to them for almost 20 times one Agent said he will remove my name from the database.I thought it would stop but it did not. It's like harassing a person with multiple calls.If I get a call again I'm going to file a complaint in the consumers court.
