Renault review: Sandero Stepway plus 900t

bought a new Sandero plus last year August from Renault Bloemfontein. The car currently has 8000km on the clock and the engine light came on. I phone roadside assistance and they said that they will sent someone to look at the vehicle. They never sent anyone. Just a lowbed and loaded my car and left me without a courtesy car and I ended up missing my little girls provincial hockey trails. This morning on my way to work the engine light came on again. I'm not in the mood for a fight like the previous time and I really need your help. I'm paying a arm and a leg for the vehicle and the service from bloemfontein is rediculous. Please assist me, I'm tired of this situation.
