Can Fin Homes — Not returning the Original documents after paying the complete loan amount

I (Sridhar Gaddam) holding a home loan account in Can fin Homes Limited #[protected] and i was willing to close the account by paying the total amount. But the institution asked me to hold for 45 days. Some how they accepted the pre close request (after complaining in CPGRAMS) after a month and i paid the complete amount. Now they are not returning the documents to me. somebody said it will take a week to get the documents. i waited for a week and when i tried calling that person, he is not responding to my calls and WhatsApp chat. somehow i was able to connect to a person working in that bank and now he is saying it will take 15 days to get back your documents.
I sincerely urge you to look in to the issue and ask them to provide the documents.
