Let me join this thread and explain how we can transfer the primary admin to you, Marcelo.

Firstly, if you contact our Support Team to request a Primary Admin transfer but you're not authorized, we will have to get in touch with the primary admin. This process is in place to prevent fraudulent activity and similar issues.

Since the transfer did not go through successfully, we can let your business partner transfer it to you without calling our support team again. For further information and detailed guidance, refer to this article: Change the primary admin user in QuickBooks Online.

If the primary admin or contact can’t transfer the role to you, they can send a request to our account protection team. You can check out this article to learn how to do it: Request to be the primary admin or contact.

Also, please understand that QuickBooks does not offer support via email. We primarily support through Chat, Phone Support, and here in the Community.

Additionally, you can check this article if you need to change your business name: Change your business name, contact info, or EIN in QuickBooks Online.

You can always post here in the Community if you need further assistance transferring the primary or have any QuickBooks-related concerns.
