Bharat Sanchar Nigam [BSNL] — The bsnl modem has crashed and not woking

Address:

641015

I am from coimbatore and after repeated complaints my problem has not been solved.
The BSNL in charge whenever picks up the phone ask me to call other number and transfers the responsibility to others.
I need the broadband for my projects. I will be grateful if the higher authorities looks into the coimbatore BSNL Branch. My land line number is [protected]
Thanking you
