I have never been able to apply for a developer account

On September 29, 2020, I tried to apply for a company developer account. So after applying for a new apple id, and then downloading the Developer APP as required, I successfully logged in to the Developer APP, filled in the real personal information, and passed the video verification. Then, after clicking "register now", an error is displayed: "Contact us to continue the process. There may be a problem with your account, which needs to be resolved before the registration process can continue. Please contact Apple Developer Support.

So I contacted Support on the Developer APP and got a call back. They said to deal with my problem as soon as possible.
But to today(2020.10.1), it is still unable to proceed to the next step. Every time I clicked the register button, I was prompted with the same error message above.

What should I do?

My Apple ID : redovecn@outlook.com
ps: My apple id is redovecn@outlook.com.
