Disgusting service

Good day, I'm reporting the bad,poor, disgusting service I received at Ford the Glen from first day when I took my car for repair. I booked my car for service on the 9 June 2022 and the whole day my car was not service and I was told they didn't get time .I escalated to the principal dealer who apologized for what happened and loan me a vehicle. The job card is clear but they replaced parts without addressing the root cause. Later the following day I collected my car and I was assured the car is fixed. But as I drive home I could hear the same problem. I took it back and we tested the car with the foreman and he told me to bring the car again ,alleging that the fitted part is not correct size he will do measurements and put in the right parts. On the 20 June 2022 I took the car to them with hope that my car will be fixed eversince they have qualified technicians. But when I came back to collect my car,I'm told the problem is not fixed hence they require me to bring the car again. I felt like I can fall down ,I felt so aggrieved and frustrated. I have to stop working and cancel my trips ,infact I'm so inconvenienced by the whole situation.
