Airtel — deactivation of broadband account

My airtel broadband stopped working in February 2020. I had called customer care multiple times in the same month but the issue was not resolved. I asked for deactivation of the services on the call, but again nothing was implemented.

After that, the landline that was provided to me with the broadband stopped working and there was no way for me to reach customer care on phone. I sent an email to airtel customer care on March 21, 2020. I got no response, it has been more than 25 days. Moreover, I get a call on my mobile every now and then to pay the bill for the last two months, but when I ask them to discontinue their services, I get no help in the same.
