Land line[protected]
I am using bsnl land line from 1973 onwards.
I got broad band connection in 2008.
Modem was supplied by bsnl.
It was working till 3rd october. 2018. It was tested at bsnl exchange and found not repairable. New modem was suppled by bsnl and connected. But there is no internet from modem. Please resolve the problem.
Or else i have to go to other service provider, which i do'nt want.
