Is it worth paying an annual fee on a credit card?

Short answer: no, EMI on credit card is not cheaper than a personal loan for large amounts (>₹50,000). The processing fee (~₹199-₹599) plus the interest (~14-16% reducing) usually adds up to slightly more than a personal loan rate of 11-13%. But for small-ticket EMI (₹10-20K), it is fine.

Forex markup comparison: Amex = 3.5%, HDFC Infinia/Diners Black = 2.0%, Axis Atlas = 3.5% but with milestone fee waivers, ICICI Emeralde = 3.5%, Standard Chartered = 3.5%. If you travel more than twice a year, the math favours Infinia or Diners Black.

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.

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.
