Complaint to Ford

On the 24 of April I went to Ford in Tzaneen wherein my aim was to service the car only to find that my car was not due for service as they didn't write in the previous visit. So I decide to suspend the service but decide to go for mechanical issue with them. There was a strange noise in my car and I requested them to check on where does it come from. They did that and later told me that the strange noise is because of the link stabilizer bar, kid brake lining, deposit cleaner, skim disk and the I said u can include the thermostat which I ordered before. The money costed R8786.09. But above all this the told me that they don't have some other parts with them they can have them the following day. So we agreed that I willl come back the following day. I had to travel from tzaneen to giyani and giyani to Tzaneen again. On the 25th of April 2023 I went back to Tzaneen. So the started with the car later when they were about to knock off the mechanic called me and told me another story to say the noise is still there and is because of bearing of R1282. 44 and insultor stabilier of 329.02 and he will need also the labour of R1275. .And the engineering of 1000 and the total balance was R4469. 43. Adding to the initial amount indicted above and also they didn't have parts they wanted me to visit again the following day. I ask the mechanic that haven't I gave you guys the car the check the strange noise so that we fix? You just took my money and not deal with the noise. I didn't know how to fix the car and I didn't know the cause of the strange noise hence I gave it you to check on my behalf and you failed me guys. Since well they were knocking off I took my car to giyani and to my surprise is that the car was worse. My question is what is it that my money was doing if it is worse this way. Yesterday the 26 April 2023 I called them to lodge a complaint and I spoke to the Ryan who responded to me to say who is responsible for that I said is them Ford as the dealership that I visited and gave them my car, his response was he didn't broke the car iam the one who broke the car, I don't know how. He was not showing a remorse. Help me I'm so drained I can't cope knowing that my car is worse than before. I trusted them as the dealership where the car comes from. Where can I rely if the situation is like this. What do I do with this kind of a car which I wanted them to fix but they did parallel fixing. Help me I'm so drained Thanks
