Rude consultant Othemba and poor customer service

I just called Selldirect with regards to a router which I ordered on line. A very rude consultant Othemba who wasn't willing to assist he kept on shouting at me and to top it up he put the phone down on me. I need my SIM card to be activated, I received my package Wednesday already but still I can't use it as it says no connection. What is the point of delivering the router to me if I can't use it. And also address your consultants accordingly so they can give the same information. I'm very irritated by the service I received from Othemba and at the fact that I can't use the router delivered.
