How to dispute a wrong transaction on my credit card

I have had a hard time getting this card approved twice. The third time I applied after a 10% salary hike and got instant approval. Banks re-check eligibility every time. If you got rejected, improve your income proof / CIBIL and reapply after 6 months.

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.

I've been using this card for over a year now. In my experience, the rewards are decent but the real value is in the lounge access and the milestone benefits. Make sure to read the fine print on the welcome benefit — most banks only credit it after the first transaction, not on approval.

The 'minimum due' trap is real. Banks love it because they charge ~36-42% interest on the carried-forward amount. If you can't pay the full bill this month, pay at least 50% — anything below that and the interest eats the rewards of the next 6 months.
