Thanks for getting back to us, Whittade.
Allow me to chime in and help ensure this is taken care of for you.
If your vendor is using a third-party app for payment processing, as mentioned by my colleague above, I suggest reaching out to them to know more about the cause of the error.
On the other hand, if they're not using a third-party app, I highly suggest contacting our Support team again. They have tools such as screen-sharing (remote access) that can check the error that you're getting and verify its cause. They have also perform some troubleshooting steps if necessary.
Please refer to these to reach them:
In the meantime, I recommend visiting our website for more tips and other resources you can use in the future: Self-help articles.
Please post again or leave a comment below if you have more questions about this or anything else. I'll be more than willing to help. Stay safe.
