complaint issue: my telephone and broadband connection have been off for more than 3 months now but despite repeated complaints there has not been any solution.
I registered the complaint with bsnl numerous times and every time the automated response says out my complaint number and that technical work in progress.
However i have been recieving bills for all these times with the last bill generated on 04.06.2016. Do i have to still pay ????
is bsnl providing me any service for which i have to pay ????
kindly resolve the issue. I am a software engineer and my work "sadly depends on internet". Isn't 3 months a lot of time???
thanks
