How to dispute a wrong transaction on my credit card

Two things nobody tells you: (1) GST is charged on the annual fee, so a ₹1,000 fee becomes ₹1,180. (2) Reward points usually have an expiry of 2-3 years. Set a calendar reminder to redeem before they lapse.

On the add-on card: yes, the primary cardholder is fully liable for all spends on the add-on. There is no separate credit limit or statement. So only issue it to someone you trust absolutely — spouse, parents. Not friends, not siblings you have money disputes with.

On credit limit increase: most banks auto-review every 6 months. If you use 30-70% of the limit and pay in full, you'll get an automatic increase. Don't call and ask for it explicitly — banks take it as a sign of credit hunger and sometimes lower the limit instead.

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.
