Kotak Mahindra Bank — Home loan closure

Address:

560047

My home loan got closed in 2015 august. I went to the bank for closure, and gave a written letter, but did not get response from the bank. I also, did not check with the bank.
Later, i updated the bank that am busy and would be collecting the documents soon. But, still no confirmation.

On 2nd may 2016, i visited the home loan section in mission road, bangalore. The lady who interacts with customers told me that i will get a call within 10 days, but still not update.

Am mailing them since then, but there's no initiation of closure. And i have not yet received original documents from bank.
