I am not able to make payment for my certification exam

The behavior described matches a Pearson VUE account block that typically occurs after multiple failed payment attempts.

When this happens, exam registration can start showing generic or “unexpected” errors and may stop allowing access to the scheduling/selection pages at all. The resolution is not on the Microsoft account or card-issuer side; the block must be removed by Pearson VUE support.

Action steps:

1. Do not keep retrying payments with the same account, as this can extend the block.
2. Contact Pearson VUE support using the Certification Support path so they can:
   • Check for an ERROR_VUE_WIDE_BLOCK or similar account-wide block.
   • Remove/unblock the Pearson VUE account.
3. After Pearson VUE confirms the block is cleared, return to the exam registration page and try scheduling again. If possible, use a different supported credit/debit card to avoid further payment failures.

If the issue persists even after the block is lifted, contact Certification Support again with the exact time and error message so they can review the transaction logs.
