NO STUDENT SUPPORT

My Son goes to Stadio. Firstly, after registration we noticed on the online-classes day that there were no courses on his canvass. We called Stadio and that was fixed. Last week again when he tried attending online he noticed that he only has 2 courses on his canvass. He sent an email to student support, I called student support and was kept on hold for over 10 minutes each time we called. I chose the student recruitment option and the call was immediately picked up. I asked, is STADIO only efficient in recruiting and then no student support. I sent an email to Finance and the lady said I'm shouting. This morning my son still had his canvass with 2 courses. Is STADIO only good with advertising and student recruitment? Can the students also be supported!!!???
