Policybazaar — disturbing calls

I have created an account in policybazaar around 1 year back for checking the service they provide, an i am not interested in the policies or investments or any service they provide. I have informed them about this. But they are calling me multiple times in a day. It is very disturbing during my work. I tried to unsubscribe from the calls, emails etc, but they are giving an option to either unsubscribe from call or email, but not both. This may disturb my emails as well as i am already getting other important emails. So i somehow want to get rid of these disturbing communications.
