BSNL — Disconnection without reason and notice

Sir,
I ported my mobile connection([protected]) from vodaphone to bsnl. After one month without any notice BSNL disconnected my phone. I personally visited thiruvananthapuram office. Most of the officials I contacted was not able to give a clear answer. They informed that this was done by a particular official and he is on leave today and he only know the reason. Finally they guessed that I may have pending bill with my previous service provider. Then I approached my previous service provider to clear. my dues if any. They informed that they have adjusted my final bill from my deposit and they cannot accept anymore money from me. It is heard that this is done by an illegal association of BSNL employees to favour private service providers to abstain people from porting phones to BSNL I informed this through mail to [protected]@bsnl.com on 12.1.14 and send a reminder on 16th. But no response. I registered complaint in BSNL portal on 16.1.14. As I'm leaving far away from Thiruananthpuram
I am not in a position to visit thituvananthapuram again and again. Now for more than three weeks my phone is not functioning. I am expecting a reply from BSNL regarding rent for the disconnected period and Is it possible to provide service to me in future or my only option is to port back to Vodaphone.
Kindly advise BSNL to give a reply to me.
