Here at Zenva Academy, we use PayPal and/or Stripe to process all transactions. As these are external, third-party payment services, we do not have access to credit card/payment information directly.
Unfortunately, due to these limitations, we are not authorized or able to give support in any way with credit card/debit card-related problems.
If you're having issues with your credit card/debit card when trying to complete your transaction, please reach out directly to your card service provider, your bank, PayPal, and/or Stripe. As these services have more direct access to your payment information, they should be able to provide more support than we can on our end.
Alternatively, you may wish to simply change your method of payment to expedite the process.
