How to increase credit limit on Kotak Mahindra credit card?

I have been using my Kotak Mahindra credit card for 12 months with a clean repayment history. How can I request a credit limit increase, and what factors does the bank consider?

Dispute process that worked for me: I called customer care within 24 hours, raised a dispute via the netbanking portal (uploading the receipt showing I never visited the merchant), and got a provisional credit in 5 working days. Permanent credit came after the bank's investigation in about 30 days.
