My bsnl has never disconnected for even one hour since 3 years
Guess im lucky!
@abhinavmail1,yes,you can ask them to reduce bill.if i remember correctly if service is disrupted for 3 days or more(because of bsnl fault) you are eligible for bill reduction for those days of no service.write an application to Accounts Officer(AO).(ask for the AO office in your local exchange,he is the one who handles all issues related to billing).
