Hello @Nguyễn Bình - Thank you for your post!
We can transfer the subscription to the company account. To do so, you need to file a support case with Azure subscription management team. The ticket enables you to work closely with the support engineers and get a quick resolution to your issue. Here is the link - https://learn.microsoft.com/en-us/azure/azure-portal/supportability/how-to-create-azure-support-request to create support case.
Note: Azure billing and subscription management support is free of cost.
