Poor customer service

I have spoken. to sifiso Imtolo and he refuses to assist me as he refuses to speak to his manager to assist me with my upgrade. he has said to me that he will not put me though to someone ells and he has been trained to do his job yet when i explain to him that there is a prob with your new system he has explicitly told me i dont know what im talking about and he knows his system. refusing head on that he is right i his word is god..
