Tutorial Campus *****

I am a student from UNISA, I have never signed up on tutorial campus's sight or had any contact with them. But I get a 100 messages everyday from them (always a new number), promoting study bundles. They have ****** my details from UNISA and spam me daily without my permission. They are a ********** company offering **** services to ***** money from students. When I phone them, they do not pick up and avoid me requests to stop spamming me. Other students have paid them money and never received their study bundles. They are *********!
