Worst mechanical and customer Service EVER

Over a year later and here I find myself still fighting with Renault South Africa,<br> From Dec 2014 to date CPU box change along with New Battery,Engine was redone which cost me R34000,ECU sensors were changed ,Diff was replaced ,Particle Filter was changed ,Starter was replaced ,The Driver door was not locking ,When the car was delivered back to me 2 weeks back, The Radio does not work and I have a grinding sound coming from the front right.This Saturday the Check injector lights remain on, So in addition I have 3 new problems as of when I got my car back.<br> During this time , I have not missed a single payment on my car.I got told last week that Renault SA will be handling this. To date no feedback received.<br>
