How to close a Kotak Mahindra credit card permanently?

I've been a customer for 6 years. The biggest upside is the customer service. The biggest downside is the slow mobile app. If you do most banking on the app, test the app at a branch before applying — it's surprisingly old.

I had the same dilemma. The way I decided was: list down my top 3 monthly spend categories, calculate the rewards on each card, and pick whichever gives the highest cashback on MY pattern. Generic 'best card' lists are useless for personal decisions.
