Can't get a new subscription again

I has a problem for get new subscription.

Detailed my case:

- In Apr 19, i deleted profile (my subscription expired in Apr 19, 2024). 

- Got email confirm for deleted and Invite to Dev Program.

- Today (Jun 20), after wait 60 days for delete current profile.

- I visit join developer page and join again.

- But, I got same screen in Apr 19, it include a old subscription expried and no any button for register new subscription/subscriptions.

- I deleted profile again (Jun 20)...

Also, i read all document and faq in Microsoft Learn for Microsoft 365 Dev Program but can't help more.

I try click to Support in Navigation(Menu) bar in top of page, redirect to Microsoft ServicesHub and can't use my account for login.

And my question:  How can register subscription again, and how can contact to support via email?
