IIE Rosebank College de-registered me without my knowledge.

I am a student at IIE Rosebank College braamfontain ohh I thought I was, today when I tried to log in my student portal it says I'm blocked and when I tried to log in a query on RC assist it says my student number is not found, I'm also blocked on outlook for what I don't know... I'm sick and tired of IIE Rosebank College treating me like I study for free... I'm supposed to register for the last module of which it was not available in first semester, I was told that Economics 1B is only available for second semester now that I'm trying to register I'm told that my student number is not found. Why do I have to go through this every year?? This time around I'm going to expose them on social media.
