Indiabulls Dhani — Stop calling again and again

I have my account on dhani. I did not know that they charge subscription fee for their dhani freedom card. It was not written any where in the app except you start the process and upload your documents. Now they show the notification of subscription. I don't want to give them the money for one month use of the card. I can borrow money for one month and my friend will not charge me atleast for one month. I stopped the process where I was. Now they are calling me again and again asking for the complition of the process and to activate the card. I refuse them for the same. But looks they don't want to understand. I have the call recordings in which I am saying 'I don't want the card or any credit, reject my application and don't bother me.' they say you will receive the calls untill I accept and activate the card. Looks like they are threatening me.
If you ( dhani) see this complaint then you should know that i am going to take legal action of harassment. Soon you will get a court notice after your reply to my mail.
