From the Credit Card Terms sheet:
How we apply payments?
We may (but need not) apply payments we receive to pay:
- fees, charges and interest shown on any statement; then
- any cash balance shown on the statement; then
- any other balance shown on the statement; then
- any cash transaction not shown on the statement; then
- other transactions on the account not shown on the statement
Not any different from how it’s done for HDFC’s Platinum Credit Card. One late payment or one cash withdrawal on your credit card and you’re milked to the extent possible.
