A court letter, even from small claims, is something you don't ignore. Last I checked, FANG do show up to small claims court, because loosing there is enforceable by law which can get expensive to ignore, if the accuser is willing to let things escalate.

In GDPR cases, you don't go to court, you go to your local data protection agency (pray you don't live in ireland). They will contact Amazon and ask for a statement. Ignoring them isn't something you can do if you value your revenue, because unlike single customers, the agency's task is to go after you with a problem for years, ghosting doesn't work, and they can issue legally binding fines you can't ignore.

Enforcement of either a court order or fines is easy if you got the title on them. If they continue to ignore you can probably get an attachment order, ie, you plus a court official plus some police officers arrive at the nearest amazon HQ and will demand the fine to be paid or they start taking company property to be auctioned off to pay for the fine.

Alternatively you can have a letter delivered by court service, which also is hard to ignore because the court service will require someone at amazon to be read a cover letter, followed by a signature and rather official stamp. After that your letter is considered to be proven in content and delivered. That is something that raises a lot of red flags in legal departments.
