Bharat Sanchar Nigam [BSNL] — application for new connection not processed.

Address:

Bangalore, Karnataka, 080

I had raised a request with bsnl for new connection. Pre-lead no:[protected]. 4 jan 2018

A agent named ketan ([protected]) contacted me and asked me to fill up a new connection form and charged me 500 rs + 200 rs
I have not received a new connection yet.
When i contacted ketan, he asked me to get the contact number of the lineman and inform him to add a new connection. I dont know where to get the contact of lineman

I tried to contact the bsnl helpdesk multiple times, but they did was put on hold and disconnect the call.

I urgently need this connection. Please let me know who can i contact to set up a new connection
