Terrible service at Renault Durban

I’ve had the worst experience dealing with Renault Durban, I took my car in for service a month ago, a few days later my engine light pops up and it persists for almost a week. I call them to book another appointment. On the follow up appointment I was told I had to change my battery, that’s why the engine light was coming on. Mind you, my car has less than 25 000 Kms on it, I’ve never had problems with a low battery or even experienced any signs of it. I agreed to have the battery replaced thinking they were doing what’s best for me and my car. I was also charged labor costs which shouldn’t have been the case since this was a follow up from service. A few hours after the appointment the light came back on, I was given another date which was today. I arrived there and was told my car would be ready at 4pm! I explained that I have to get to work before that time and I was told that there’s nothing they can do. I’m extremely disgusted by the service, they do not care for the customers needs and safety. I would not advise anyone to service their car at Renault Durban
