I can't use custom domain error

i want using hosting and domain so i payment for custom domain but it’s error
‘Unable to order domain with this domain name. Please contact support with the domain name for the assistance.’ but the money was paid twice in my bank account. so i can’t use my domain but it’s been registered ‘https://app.netlify.com/teams/tsumulingu/dns’ what should i do?

The team will probably need more information, such as the domain name in question.

Does this document help?
