I cannot enrol and now the button is in grey

I tried to enrol and because I have logged in my computer with an account and it shows not support my account etc. therefore I logged in another account on the Developer App, it went smoothly at the beginning. Then it took me to the yearly subscription and showing billing for the account on my computer. I thought this was not okay. Therefore I signed out the account on my computer and logged the same account as I used for the Developer App.

I restarted the process. Filled in basic information, address, then Next. Boom, it said something was wrong and I needed to contact support. I did, but they told me there was an error indication for my account, no solutions what I could do.

So what? I am forever not able to publish on Apple Store? Does it mean I should continue my test flight on Android? What's wrong with this? Who could help me?
