VW Middelburg dragging its feets while I suffer

I bought a car from McCarthy VW Middelburg three weeks ago but the car has already had more than 4 different mechanical issues.

They asked me to send the car to their McCarthy VW branch in Durban. I have been to the VW Durban branch for 6 working days trying to get the car fixed and it is still not fixed.

I have found myself watching their communication going back and forth between the two branches discussing who will be responsible for the costs. VW Middelburg is not treating my issue with the urgency it deserves while VW Durban is also not helping the situation.
