Error when entering to take my exam for CKA

I’m the one who registered to take the CKA test on Saterday (22.04.23).
I finished all the procedures before the test began and pressed the test start button, but the screen was not redirected and only the wrong screen came out, so I couldn’t take the test itself.
I’d like to make a strong protest that I haven’t found a solution to the problem at all, and that I missed the test opportunity itself 1 time because of a technical problem.
