This looks like a billing form validation issue rather than something you’re doing wrong. Most payment systems verify the postal/ZIP code against the one your card issuer has on file, not just the address you enter. Even a small format mismatch can trigger that error.
Try entering only the ZIP/postal code (no spaces), typing the address manually instead of autofill, and making sure it exactly matches your card’s billing details. If you’re outside the US, some forms expect a specific ZIP format. Also, if the Contact Support link is broken, check their Terms or Privacy page for a direct support email.
I’ve run into similar checkout issues while working on guides and site features over at https://stardewapkvalley.com/ , and it usually comes down to how strict the payment processor is with billing info.
