Horrible customer service at Renault East London

On the 30th August, my car broke and was towed to Renault East London. They diagnosed a failed timing chain but refused to repair it, citing the wrong oil used by Car Service City (5W30 instead of 5W40). Car Service City emailed service specs from Hynes Pro, but Renault still won't fix the issue. My car is still under warranty . Renault has also emailed me the specs for servicing their cars but according to Hynes Pro, it’s 5W30 that is supposed to be used. At this point I am so lost, I don’t know what to do next.

I have escalated the matter to the Motor Industry Ombudsman and they forwarded my complaint to the cfao motors group. We are still waiting for their response.

I am more that willing in forwarding all the emails I have with both Renault and Car service city.
