Airtel - AIRTEL Sending Postpaid Bill Without Services

Regarding *** Plan | ********** | PLAN CLOSURE
==========================================
As our BUSINESS is closed and every month we are getting the postpaid bill of INR ***. A Late Payment charge of INR *** has been added this month. We asking for deactivation of postpaid connection for * months but no one has acknowledged so far.

Is it like, till the time we have a lockdown, the service provider can keep sending the postpaid bill?

We are asking again and again for account closure but no one replying, even the Airtel executive who provided *G connection not acknowledging us.
Your backend APIs are also not working for Postpaid Number w.r.t SERVICE REQUEST [Screenshot Attached]. Check your servers' LOGS. If Services of AIRTEL THANK APP is down then the customer can't do anything here.

No way to reach AIRTEL. Trying for * Months.
We are blocked here and every month POSTPAID BILL keeps on coming also your customer care keeps calling and mentally harassing us.

As I am not getting any reply from anyone. I have not received any single mail from airtel regarding deactivating the postpaid connection that I have been requesting for the last * months. The irony is that bill-generation is happening on time. Why Bill Generation Services (REST API) are UP and REST all services (for deactivation Request) are DOWN?

No one from local airtel executive helped me
Neither Airtel-App, as backend services are down since the last * months for raising request
Nor any reply from any airtel executive in the mail
FYI, even though you are charging for the internet service, but service is also down since a long time
Services are UP for taking money and bill generation, but those services where people may raise disconnection requests are down. I see television ad, where Airtel is with common people but don't see that happening on the ground. See the below mail thread running from the last * months. Why no one ever replied? Why e-bills are getting generated every month but people deactivation requests are not being considered? Why your backend services are not up and running (Airtel Thank App)?

NOT HAAPY AT ALL WITH AIRTEL, ITS SEEMS THAT YOU ARE ENFORCING POSTPAID BILL ON US DURING LOCKDOWN AND FORCING US TO PAY THE BILL. FIRST CORRECT YOUR BACKEND SERVICES AND PROCESSES, ALSO TEACH YOUR CUSTOMER CARE HOW TO TALK, THEY ONLY KNOW ONE LINE, WHEN YOU WILL PAY BILL? FIRST TEACH THEM THAT YOUR SERVERS, SERVICES were not WORKING during LOCKDOWN. The problem is on the AIRTEL side, not at End User.
