Migrating from an Individual to an Organization account

I've requested the migration about 4 weeks ago.

I received an email from Apple Support about 2 weeks ago, that we can start with the conversion of the account from "individual" to "organization". The message itself offered no actual instructions on how to do that, it just laid out the steps I had already taken to do the conversion.

I've requested an updated to my case 9 days ago and still no response.

Please advise.

Thank you
