Oracle Cloud: Sign up failed... [2]

After my failed registration to Oracle cloud, i got very fast an email from Oracle support with the following requirements:

So i tried once again with a firefox "private" window - but this failed again.
Next idea was to use a completely new installed browser: so i tried with a fresh google-chrome.
But the error still remained:

Let's hope Oracle support has another thing which will put me onto Oracle cloud.

UPDATE:

 

There is a tiny link "click here" just abouve the blue button. This link a have to use with the verification code provided by Oracle support.
But then the error is:

I checked this a VISA and MASTERCARD. Neither of them worked...

UPDATE 2: see here how the problem was solved.
