Airtel — Not solving my Network Problem and My Complaint

Address:

Airtel Telecom India.

I'm using Airtel Black Postpaid Connection since January 2022.
I was promised that i will be getting great service and better internet Connectivity than prepaid.
I'm facing lot of internet Connectivity issue since day 1.
I'm complaining them every 15 days once, they will take complaint request and close it automatically after 15 days.
But the problem hasn't solved yet.
My monthly bill is clear, I've paid them on time.
But they are not giving me proper service.
I'm being cheated from around 10 months.
If Airtel is collecting bill from me, then Airtel should provide proper service also.
I have all proof and Call recording of customer care people, i want Justice.
