Worst Renault Dealership

My renault had broken down and was towed to the nearest dealership which was unfortunately, Renault Ontdekkers. My car went in during working hours on Friday. I was told that the car will be seen on Tuesday as they do not work on Saturday and there's a public holiday on Monday. On Tuesday I called the service department over 5 times to find out if the vehicle was checked, there was no answer and when someone answered they said they would call me back but didn't. After spending 5 days without any info about my car, I called the dealership early Wednesday morning, I left my details again and no one called me back. Eventually after consistently calling the branch a lady from the service department answered and spoke in a rude tone as I was enquiring about my car. She told me that there's a 48 hour waiting period for my car to be checked, I told her that no one told me this when car went in on Friday. She also mentioned that the service department was in fact opened for half the day on Saturday but that day didn't count, nor did the public holiday so Tuesday was in fact the first day of the inital 'waiting period'. She was unhelpful but I finally got to know the name of service advisor who was meant to be dealing with my case and communicating with me. Portia my, service advisor contacted me late Wednesday afternoon to tell me that the car had been tested and they needed to call someone from head office to check my car as they did not know what was wrong with it. About an hour later she calls to say that they found it was the airflow meter, they cleaned and the car is fine. Im not sure how they found the fault so that quickly, if someone from head office was meant to go to the dealership. Portia went on to say that I should pick my car up from the dealership. I told her that I didn't have a lift to pick my car up and she said that I could come tomorrow. She didn't use the shuttle service that every other Renault has to transport their customers. She didn't offer nor was she interested in how I got to the dealership. So at my own cost I had to go to the dealership. Upon my arrival, Portia gave me my documents so I asked her why the management light on the dash didn't come on if the airflow meter was the problem. She gave me the same response as she did over the phone as if the script was rehe****d. She said they cleaned the airflow meter and I should bring it back if the car does the same thing and they will replace it. As I was leaving, Portia made a remark about me asking questions to her colleague in tone that was offensive. She was offended that I enquired about my vehicle. Is that not what her job is about? To help clients and answer their questions and to put their mind at ease. I feel more anxious about driving my car now than when it actually broke down. I didn't speak to her further and left. My car has lost power even though there's 18k on the the meter. I will not take it back to this Renault as they are unhelpful, not customer centric, they have bad attitudes, there's no ounce of professionalism, poor communicators and just plain rude! I have dealt with Renault for over 10 years and this is by far the worst branch. I have contacted another branch as they are customer centric and actually value their customers. Please do not use this Renault branch. I would've given it Zero Stars if I could.
