Muthoot — noc of loan

Address: KANNUR, Kannur, Kerala, 670631

I had taken a bike loan from muthoot finance. I already completed my loan amount and i have no due. And i requested noc to change my rc. But they didnt give me yet. My loan is closed on 2018 january. I went their office many times but they didnt resolved my issue yet. I want to sell my bike.. So i need to change rc address soon.. I am here stucked with their dirty behaviour. Please make necessory action against them. I can sent the loan details and certificates if needed.
