Horrible service

My vehicle broke down on 8 April 2022 in the middle of the road, no prior warning, no nothing. I tried to contact road assist but my call was dropped twice. I had to contact my sales person who also had trouble getting hold of road assist. My car was finally collected 2 to 3 hours later while my young children and I had to make other plans. On 9 April 2022, my vehicle was said to be delivered to Menlyn Mazda around 11:30. I received no call from Menlyn to say that my car had arrived. I asked for the dealership manager who then got the service manager to contact me. 10 April, my sales person from Witbank made plans for me and my girls to return home as we have a family holiday on 12 April. 11 April I had to contact Menlyn so many times just to get feedback or a courtesy car from them. They spent time eye diagnosing my car instead of putting it on the diagnostic machine. Eventually they say that the problem is incorrect fuel going through the system. I informed them that I always use more or less the same fuel garage. I ask for a courtesy car as I am due for a trip with my girls and they inform me that only a Swift is available. I informed them that I would need something bigger due to the size of my family but they say they can only give me the said car and also the damage to the car is not under warranty. I asked for the manager's car and didn't get a response. I was informed that I would be called on the 12th in the morning but nothing. Called the manager, no answer. Called again a few hours later, he said he was on a call with Hatfield. I still have no idea what is to happen with me and my girls or my car. Horrible service from Menlyn and great customer service from Witbank (JP and team).
