Chery Qq3 which can't be fixed by qualified Renault/Chery agents

Chery has a joint venture with Renault in Roodepoort and I took a small Chery QQ3 that's in limp mode to get sorted by the Chery experts. After some time to get it booked and repaired, was a mission. I booked it for service just to get the engin management light off cost R3200 and they give it back with the light still on. After being unhappy with this experience I was sending a mail to Chery SA, they sent me back to Roodepoort and now it was my timing that was out (after it just came back from a service). It cost me another R5400 for the timing and got it back and nothing has changed. Even the light is still on because the don't have spares to fix. A cost of R9000 for the smallest car on the road to sort a engin management light with no results. I feel ****** and sit with the same problem with the car still not running normal.Still in limp mode, and nobody from Renault Roodepoort ( Chery SA agents) and from Chery SA to give me a call to find out if the problem were sorted. They are happy with my R9000 and me with a dent in my pocket with no results must be happy and do nothing. I would be happy if there is a qualified Chery mechanic in SA with knowledge on how to fix this car to assist me.
