Mistakes, Fraud and Complaints
Credit card mistakes to avoid in India: 12 costly errors with cashback and reward cards
The most expensive credit card mistakes in India — revolving for rewards, minimum-due payments, cash advances, DCC, missed waivers, fraud delays — with rupee examples and official sources.
The costliest credit card mistakes in India are almost all about interest and timing, not rewards: carrying a balance while chasing 1–5% cashback, paying only the minimum amount due, withdrawing cash, accepting "pay in INR" abroad, missing a fee waiver by counting excluded spends, and reporting fraud late. A single month of revolving ₹50,000 at an illustrative 3.5% a month costs about ₹2,065 with GST — more than many cards return in a year. This guide lists twelve common errors, what each costs and what to do instead, and ends with the official sources to check. Figures are illustrative.
This is the overview guide for the section on mistakes, fraud and complaints. It is general information, not financial advice.
The twelve mistakes
1. Revolving a balance on a reward card
Rewards of 1–2% cannot offset interest of about 3–4% a month plus GST. Pay the total amount due, by auto-debit. See credit card interest.
2. Paying only the minimum amount due
It avoids a late fee, not interest. A ₹50,000 balance paid at the minimum can take over 20 years in an illustrative example. See the minimum amount due.
3. Taking cash on the card
Fee, interest from day one and GST: about 7% for one month in our example. See cash withdrawals on a credit card.
4. Counting excluded spends
Rent, wallets, fuel, insurance and utilities often earn nothing or are capped, and may not count toward waivers. See reward caps and exclusions.
5. Ignoring GST on fees
A ₹2,500 annual fee is ₹2,950. See GST on card charges.
6. Accepting dynamic currency conversion abroad
"Pay in INR" can cost several percent more than paying in local currency. See forex markup and DCC.
7. Applying for many cards at once
Each application can add a hard enquiry. See credit cards and CIBIL.
8. Running utilisation near the limit
Even if you pay in full, a high reported balance can weigh on your score. Pay part of the bill before the statement date if you spend heavily.
9. Letting points expire or losing them at closure
Redeem first. See reward point value.
10. Reporting fraud late
Within three working days, a bank customer has zero liability for third-party fraud; after seven, the bank's policy decides. See credit card fraud and zero liability.
11. Accepting upgrades or limit increases on a call
Issuers need your explicit consent; ask for the new KFS and fees in writing before agreeing.
12. Keeping an unused paid card
Close it after redeeming points, or downgrade. Closure must be done within seven working days if there are no dues; see closing a credit card.
What these mistakes cost (illustrative)
| Mistake | Example | Approximate cost |
|---|---|---|
| Revolving ₹50,000 for one month | 3.5% + GST | ₹2,065 |
| Cash advance of ₹20,000 for a month | 2.5% fee + interest + GST | ₹1,416 |
| DCC on a ₹8,500 bill abroad | 4% DCC margin + card markup | about ₹354 more |
| Missing a ₹1,50,000 waiver by ₹10,000 | ₹1,500 fee + GST | ₹1,770 |
| Late payment once | Late fee + interest + GST | often ₹2,000–4,000 on a mid-sized bill |
| Fraud reported on day 5 (₹3 lakh limit card) | Liability cap | up to ₹10,000 |
A monthly routine that avoids most of them
- Auto-debit the total amount due.
- Glance at transactions weekly in the app.
- Check the statement for fees, GST and reward credits.
- Keep a note of the waiver spend so far and the anniversary month.
- Keep international and contactless use off unless needed.
Use the credit card comparison checklist when choosing a new card.
When things go wrong
- Wrong charge or delayed closure: complain to the issuer, then the RBI Ombudsman. See credit card complaints.
- Fraud: block the card, report to the issuer, call 1930.
- Debt you cannot manage: talk to the issuer before missing payments; consider a registered adviser. Avoid paid "credit repair" or "debt settlement" agents who promise to erase records.

Frequently asked questions
Is it a mistake to have a credit card at all?
No. Used with full payment every month, a card gives interest-free credit, rewards and fraud protections. The mistakes come from borrowing on it.
What is the single most important habit?
Paying the total amount due by the due date, every month.
Should I close a card after one mistake?
Not necessarily. Fix the habit first; closing can raise utilisation.
Can I get a late fee reversed?
Some issuers reverse a first late fee on request as goodwill; it is not a right unless the fee was charged against the rules (for example, within three days of the due date).
