Bharat Sanchar Nigam [BSNL] — urgent request for a stable broadband connection

Address:

Dindigul, Tamil Nadu, 624401

I'm working remotely from home, with wireless connection i couldn't able to connect my client ip, in order to do that i was in need of broadband connection. Bsnl is the only broadband service provider in our area, so i have approached ae for new connection. My house is 350 meter away from the existing broadband pole. Since fiber cable is not available at natham branch, he asked me to go with traditional copper wire telephone line (Dsl) for time being, he also promised that once fiber cable is received from madurai office, surely he will do the cable change for me.
Upon his promise about fiber connection, installation happened on the same week with dsl. From the day 1 connection was not stable,
With this poor connection i couldn't able to connect remote for which i got this connection.

In-between twice the cable wire got cut because of wind, in this regard i have made many complaints to bsnl department. Also submitted a complaint letter to the bsnl natham on june 2018.
Despite that nothing related to fiber cable connection has been done, launched new complaint to customer support, they responded well and changed dsl to cable wire with condition basis
(Minimum 2 connection required, so i got additional connection to get rid of the problem).
But it solved only 60% of the connection issue. Still connection goes on and off atleast 10 times a day and poor upload speed. The situation is still pathetic & unsolved

I have approached customer support of other service providers (Airtel and reliance jio), they said minimum 15 connections required to start the service in our area which is impossible for me to do but
I can assure people will start getting connections once they start seeing good service. I don't know what else i can do, apart from contacting one after other. It is very very urgent.
Kindly help me to get proper broadband connection at the earliest.
