No courses under student portal

I signed up for the course in November 2021. I started it and completed a few modules. I got busy and left it for a while. When I wanted to start working on the course, they had changed the system to videos. I had to start from scratch again. I struggle with concentration, so this is not an ideal method for me. I finished a few videos though. I then wanted to continue, but there are no courses loaded under my student portal. I enquired about it, and I received a video on how to access the student portal. I then tried again, and there were still no courses loaded. I have sent 2 emails in this regard, and have yet to receive an answer. As this course is expiring soon, it is really urgent that I get to complete it.
