Payme India — Harassing calls

I paid Payment India the amount which they told me to pay to close my loan and they said that they will issue NOC for the loan closure after paying the amount they told me to pay and after that I was being told that I will get the NOC within 24 hours but they are calling me again and again to pay the loan and harassing me and threatening me and invading my privacy. I still haven't received the NOC yet from Payment India and they are continuously calling me again and again even after paying the amount they told me to pay for the loan closure, I have attached a screen shot of the conversation with Mr. Shubham from pay me India
