Harassment and spam

What an annoying company! I keep getting spam emails and smses, even after I have cancelled. I joined a 4 week course, cancelled when I realised I didn't want to do the course, got my cancellation confirmation, and thought I was done. Now I get an sms at least every 3 days asking why I left the course, don't I want to come back, why not restart the course, etc. ANNOYING! And you can't opt out of these smses, which is against the law. POPIA is coming for you, Shaw Academy.
