Bharat Sanchar Nigam [BSNL] — Landline telephone not working last 4 months-Kakinada

The Landline[protected] was not working for the last almost 3-4 months.
Gave complaint on customer complaint number, many times, (as far i remember 8 times) for the last one month.

Every time, the responder asks same questions Which number, which area, what is my contact number, and say he will send the line man in an hour.
Then i wait for two days. again call. this is the way its going on for one month. And the phone was not working even 3 months before. As i was out of station, could not follow-up.
