To clarify, did your client's credit card payment fail with an error message? If so, please feel free to attach screenshots to help us better understand the issue and provide you with the appropriate assistance.

Sometimes, credit card transactions fail due to authorization errors. This may occur if the entered information is incorrect or if the payment exceeds the bank’s limit. Below are some steps to help address the issue:

• Verify that the credit card number and verification code are correct.
• Avoid special characters or spaces in the credit card number or other data fields.
