Hello @jaylee135,
Could you please open a ticket about this from WooCommerce.com > MY profile > Support?
Make sure to include a link to this thread so we know what has been done already.
Cheers!
Hi Saif,
That is where I originally tried to log a ticket, but it popped up saying to log it here, because that platform is only for paid subscriptions.

Sorry to hear this, what you’re describing happens when you reach out to us for assistance with a problem related to WooCommerce-core. Please make sure to select the correct extension when submitting a ticket in the future.

That said, seems like the error you attached in your first post is returned when the zip the customer gave doesn’t match what the system has on file for them, and that information is supplied by their bank (or card issuing authority).
You can test this by switching to test mode and test ordering something with one of these cards.
If the problem is not present after doing so, then please ask the customer to update their credit card information from their bank or use another payment method.
Let us know how it goes.
We haven’t heard back from you in a while, so I’m going to mark this as resolved – we’ll be here if and/or when you are ready to continue.
