disgusting attitude!!!!!!!

Cartrack sales agents called to come and stall the device on my vehicle when I advice him that I don't have a contract with you guys and ask him to be honest that his offering a new product which am not interested then He was rude and hang up on me....who is he to hang up on me??? did i request his cal??? Hell no!!! I will not tolerate such behavior on my phone during my work time...... There's a new POPI Act and I'm going to report Cartrack, according to the law you cant call me without my consent.
