Bad service from Stadio Higher Education

It has been a joy dealing with Stadio until the release of the semester marks. I paid all fees for the semester, and I still cannot access my marks and academic record. When you call, nobody answers the phone. When you log tickets, you dont get any response. Re-registration for the second semester closes next week, and you must indicate on the form the modules you'll be writing supplementary exams for towards the end of the semester. How can you do that when you dont have all your marks? I'm so frustrated with this institution!!!!
