BSNL — Bsnl land phone is not working[protected]

Address:

Nellore, Andhra Pradesh

Sir,

My BSNL Land line phone is not working[protected] since 4 months. I complained so many times on online and personally about this issue to LINEMANS, AE, DE, but the phone is not working till today. When I complained the issue to BSNL officials they are telling we can solve your problem within one day and they are closing the complaint without solving it.
Also I am getting every month phone bill, even the phone was not working.
