I'm sorry to hear that you're having trouble using your debit card to add credits to your wallet. Let's try to resolve this issue together. Could you please check if:
1. The card details are entered correctly, including the card number, expiration date, and CVV.
2. Your card is activated and has sufficient funds for the transaction.
3. Your bank allows online transactions and there are no restrictions on your card that might prevent the transaction.
If everything seems correct and you're still unable to add credits, it might be a good idea to contact your bank to ensure there are no issues on their end. If the bank confirms everything is fine, please reach out to our support team for further assistance.
