How to dispute a wrong transaction on my credit card

The customer care experience matters more than people think. I've had two cards with similar rewards, and the one from the bank with better support saved me ₹18,000 when there was a merchant dispute. Don't underestimate this.

I've owned 4 cards over the last 7 years. The biggest lesson: a card that fits your spend pattern beats the 'most rewarding' card on paper. A 5% cashback card you actually use daily will give you 10x more value than a 10% card you use once a month.
