BSNL — Charged for days when no service is available

Address:

Bangalore, Karnataka

BSNL Banglore has a system of charging its customers with complete bill amounts for land line and broadband, though the service is not available for few days in a month. My landline was dead for a couple of days, yet BSNL charged me with complete bill amount for both the calls as well as broadband charges. Is this the right way of billing or is BSNL cheating its consumers.
