Idea Cellular — I want final settlement bill amount with exclude non usage bill amount.

Account number is 1927035, I was using idea broadband and faced many network issues. so I logged complain many times and it was not resolved so I disconnected and called customer care and asked them to disconnect INTERNET connection service in Sept-2019. They said it will get disconnected but They have not disconnected Internet services and generating every month bill. I also removed modem and not used single data
after raising disconnected request.

I want final settlement bill amount with exclude non usage bill amount.
