There are several reasons why a credit card may not work with online payments. To resolve the problem, you must first determine the source of the problem, some reasons may be: 1. Insufficient balance: If the available balance on your credit card is insufficient to cover the transaction amount, payment may be declined. 2. Credit limit exceeded: If the card's credit limit has already been reached or exceeded, the transaction may be declined. 3. Incorrect information: If card information (number, expiration date, security code) is not entered correctly, payment will not be authorized. 4. Security restrictions: Some credit cards have security restrictions for online purchases, such as requiring the card owner to authorize the transaction before it can be completed. 5. Problems with the payment processor: The payment processor being used by the website may be having problems or currently down. 6. Card blocking: If there is suspicious or fraudulent activity on the card, the card issuer may temporarily block it to prevent fraud and protect the cardholder. 7. Problems with our website: The problem may be with our website where the payment is not being processed correctly. In this case we will work as quickly as possible to resolve any complications. In case of doubt or persistent problem, it is recommended to contact the card administrator or Descarbonize by email at faleconosco@descarbonize.com for assistance.
