Missold by Ashley Samuals and Damien Govender

A consultant by the name of Ashley Samuals sold me a package and mislead me with his manager Damien Govender in believe I was only going to pay 399 for 24 months contacts with a once off extra charge of 100 and 75..nothing more unless malfunctioning then only will I pay 159 for services and every month after a straight 399 till my contract ends. I have been missold as my payment is reflecting at 633 which I will not pay. I want this deal cancelled as I was wondering why the consultant said I might get surprised with my bill when I receive it an yet when I reconfirmed he said I will not pay 159 unless my device don't work after the cooling off period including the manager. I'm calling the call centre they provided to me as well as on the sms but no one answers. I don't want his contact anymore for being missold and misadvised. This is *****!!!
