Bharat Sanchar Nigam [BSNL] — No response from bsnl staff after numerous complaints

Address:

797117

I am having bsnl landline connection in dimapur, nagaland.
My phone line is dead since last 20 days. Despite numerous complaints there is no response from the staff. Problem is that there is no other service provider in my area. These faults in bsnl are very often. They are very punctual in sending the bills however there is no punctuality when it comes to providing services.
