Airtel — Network issue, call drops, no data

I am facing network issue in my area for past 5+years all the time i raise airtel promises me to resolve the issue and it never happened, some of the customer care executive were rude to me . All the complaints i raised have been closed without giving any update and without resolving it. I did contact appellate authority of airtel Kerala and the is no response from them, in next step i raised issue on CPGRAMS(Centralized Public Grievance Redress And Monitoring System) even that didn't help .
I am facing call drops and call disconnecting issue in indoor and outdoor, signal is not stable, data speed is too slow i can't even sent a WhatsApp message, can't load google, no streaming in both indoor and outdoor. There is a site(tower) available nearby which airtel could use it was used airtel before currently jio and vi uses, there are signal towers which are used by three operators airtel could do the same or bring a new tower here.
