Unhappy client

I`m having a really bad service with their main boksburg branch ,as I have bought a car 3months ago with KZN registration and expired licence disk and up to this day I have not received anyfeed back from them as they always promise to call or sort out the matter.A salesman by the name of Xolani Mpabanga and his manager JP because they made a sale they don`t care anymore keep sending me from pilar to post.
