Nameservers not delegated for .be domain purchased through Vercel

I purchased moskeeaalst.be through Vercel 3 days ago, but the nameservers were never updated at the .be registry (DNS Belgium). They still point to the default nsset.be parking servers instead of ns1.vercel-dns.com / ns2.vercel-dns.com.

API Status:

{
  "nameservers": [],
  "nsVerifiedAt": null,
  "registrar": "new"
}

This is a registrar-level issue that only Vercel can fix. Please escalate.

The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for bonus points.

You can also use v0 to narrow down the possibilities.
