“Your enrollment could not be completed.” Please review my case

I am very disappointed and frustrated. I applied a developer account two months ago and is getting stuck in somewhere. After two months and many rounds of email and call communications, apple support cannot provide the reason/solution/alternatives how to proceed my application. Background: I applied an apple developer account through developer web in Mar, and received order acknowledging email from apple team. It said that it will take 2 working days for processing. However, two weeks later, it is still no news. Then I created the support ticket by email and wait for two weeks, apple support team recommended me to apply the account through “developer app” instead, then I follow the guideline to apply and encounter the ID image submission error. After few days, when I revisited the developer web and checked the status, it showed “Your enrollment could not be completed.” I tried to send several rounds of email, but got no reply for almost one month, finally, I call developer support several times, and support still cannot provide the reason/solution/alternatives how to proceed my application, they just repeated the fact of “Your enrollment could not be completed.”, although I request to escalate my case to senior technical advisor, it cannot. I am really very disappointed and frustrated. I hope someone here or apple support, please help to review my case and guide me how to proceed my application. My case ID: 102855764543. Thanks a lot.
