Kotak Mahindra Bank — credit card noc

Address:

New Delhi, Delhi, 110027

Hi, i've paid my dues in total for my kotak mahindra credit card. The recovery people were really proactive while collecting money, now no one can help me get the noc for the card. Contacting kotak customer care for credit card is next to impossible and the bank keeps routing me to an email address from where i've never received a reply.

I would need help to get in touch with a kotak representative.
