BOUGHT A NEW VEHICLE FULL OF ISSUES WITH NO HELP

Bought a new vehicle 2 months ago - not a cheap one either , hilux 3.0d4d with issues on a daily basis . Called toyota south africa a countless number of times and each jack**s in the call centre doesnt bother to respond . Vehicle sat at a local branch to resolve issues only to discover a new one each time .. what do i do to get some answers or a proper vehicle as to what i paid for . If i bought second hand i would shut my mouth , but the reason for new and a toyota was off course \ EVERYTHING KEEPS GOING RIGHT ".. i would like to mention that nothing is going right "
