Why was my purchase cancelled or my payment not recognized?

The purchase process on Mundpay is simple and fast, but it involves some release and approval steps that must be completed for payment to be confirmed successfully.
The steps are.

  • Purchase order submitted by the customer
  • Analysis and approval of payment by the bank or card operator
  • Transaction confirmation by the payment platform

  • Since more than one party is involved in this process, some factors can prevent purchase approval. Below, we explain the possible problems that can occur at each step.

Purchase order submitted by the customer

  1. Was unable to pay with this card

Some incorrect card data may have been identified. Verify the information entered or try using another available payment method.

  1. Invalid credit card or brand not accepted

Check that your card details are correct and the brand listed is accepted on the payment page.

  1. Restriction message

A restriction message may appear during purchase. This can happen due to non-compliance with the platform's terms of use or security rules.

  1. CPF (Brazilian taxpayer ID) entered incorrectly

Verify that the entered information is correct and complete.

  1. Card expiration date not provided

You must fill in the month and year of card expiration correctly.

  1. Product unavailable for sale

In this case, we recommend contacting the seller responsible for the product directly for more information.

  1. Invalid email

Verify that the email was typed correctly, without errors, spaces, or capital letters at the beginning.

  1. Error generating bank slip

Try generating the bank slip again. If the problem persists, use a private browser tab. Unpaid bank slips are automatically cancelled after the due date.

  1. Communication problem with operator

This may be a temporary instability. We recommend trying again later or contacting the card operator.

  1. Invalid card number

Verify that there are no letters, spaces, or incorrect digits in the card number field.

11. Transaction denied by card operator
Contact the issuing bank to check credit limit, balance, or security blocks.

12. Purchase already submitted in this session
Check your email to confirm that the purchase has not already been completed, avoiding duplication.

13. Invalid IVA/VAT
Contact Mundpay support so we can analyze your case.

Approval and release of purchase by card operator

  1. Card data entered incorrectly

Carefully check the cardholder name, card number, expiration date, and security code (CVV).

  1. The card entered is not a credit card

Make sure you are using a credit card enabled for online purchases. Food or benefits cards are not accepted.

  1. Payment denied by issuing bank

Even with available credit, the bank may deny the purchase for security reasons or consider it outside normal use. In this case, contact your bank to authorize the transaction.

  1. Insufficient credit limit

Try using another card or contact your bank to check the possibility of increasing your limit.

  1. Card not enabled for online purchases

Request that the card operator enable purchases over the internet.

  1. Purchase cancelled but amount appears as charged

In some cases, the amount may appear temporarily as reserved. This amount is automatically refunded by the issuing bank after a few days if the purchase is not completed.

Notice that almost every decision here is about timing, not amount. Answer the same day and you return the same money without losing the metric; leave it for later and you return the money and pay the penalty too.

My card is valid, but I couldn't pay with it. Why?

Even with available balance, the bank can refuse the purchase for security reasons or consider it outside your normal spending pattern. In this case, contact your bank to authorize the transaction specifically. It's also possible your card is not enabled for online purchases.

I received a restriction message. What does it mean?

During purchase, a restriction message may appear, which indicates there may be non-compliance with the platform's terms of use or security rules. Contact Mundpay support via help@mundpay.com providing details so the team can analyze and clarify the situation.

My purchase was canceled but the amount appears as charged. Why?

In some cases, the amount may temporarily appear as reserved on your card limit when the purchase is not completed. This amount is automatically refunded by the issuing bank after a few days. If it's not refunded, contact your card operator.

I tried to pay with boleto but received an error message. What do I do?

Try generating the boleto again, verifying that all data has been filled correctly. If the problem persists, we recommend using an incognito browser tab or choosing another payment method. Unpaid boletos are canceled automatically after expiration.

Have I made this purchase before? How do I avoid duplicating?

If you already tried to make this purchase, check your email inbox to verify if there is a purchase confirmation for this same product. By accessing your purchases area at https://orders.mundpay.com/ you can see the complete history and avoid a second unintended purchase.

A refund settled quickly costs less than a dispute opened at the bank. When the buyer can resolve it inside the platform, the seller takes no chargeback and nobody loses an account over a ratio.
