(For credit cards) Limit exceeded
Insufficient balance - Our system will make a temporary charge of P10.00 on your card to verify it. This is for authorization purposes only and the amount will be returned to your card.

Your card's issuing bank is located in a different country that where Taxumo is located (Philippines).
Your card's issuing bak may have put a temporary hold on your card.

If you think any of those are true, you can then do the following:
