[Resolved]  Bharat Sanchar Nigam [BSNL] — broadband completely out of order for 7 days

Broadband connection on my bsnl number [protected] has been down for the last 7 days.
Customer care says, it'll be repaired in 3 - 5 days but its been 1 week now. I'm suffering a lot due to this, and planning to discontinue bsnl broadband if such conditions persist...
All efforts of repair bear no results and for a student like me, internet connection is very essential..
Kindly make sure this is resolved or connect me to higher authorities or consumer court, because this is becoming an unbearable ordeal, a horrific customer servicing experience.
