Is the card already added to Payzapp? Were you charged Rs.2 while verification when adding? After adding card, for first 24 hours, load limit is 2000. In past it was like that. Don't know now whether same is applied for first 24 hours or whether limit is increase to say 5K or 10K etc.
It's always better to first add card to check whether it will work or not. Most of HDFC CC don't give any problem. But if you add/use your HDFC card on say, faimly member payzapp acc. they will first debit Rs.2 and credit back just to verify card details and whether it is a valid card. As you are using a different bank card, it may be a problem. But most cards are allowed to be used. Also check whether your online txn limits are fine.
