IndiaBulls — home loan regarding issue

Hi, i took a home loan from indiabulls 3.5 years back. My home loan account number is hhlgrg00180348. All my emis were getting deducted through my account through ecs regularly without fail. Last month i could not arrange for the emi due to some unavoidable personal problems. I did contact to rajiv and then met pankaj from collection department at indiabulls office as suggested by one of the bank's executive. Pankaj gave me the extension for one month and said that if my problem does not resolve he can extend it to one more month at max. Then after one week i got a call from customer care again for the payment and i told him that i have already talked to pankaj.in a day or so again a collection agent came to my home for the payment. I was talking to that agent for last few days and he is aware that i have talked to pankaj. Inspite of my regular request of not sending any agent to home they not even sent an agent but also threatend me of different consequences. And it is all just for one month payment. Rajiv threatened me that he will send lot of people to my home and said that do whatever you can do. Although i am going to make a police complaint but this is unexpectable. I am not a thief, i just requested for one month exemption.
