Unacceptable Service

When driven, my vehicle has a noise so I requested it to be checked at Ford CHM Kempster Umgeni when servicing my vehicle which was last week. I was then told to record the noise and bring the vehicle back this week. I took it back to today and played the videos of proof. It doesn’t sound too pleasing to drive and it seems like there’s something wrong with the vehicle. So anyway I was told to leave my vehicle and will get a call once done. I didn’t receive any calls during the time my vehicle was at Ford to state the status of the vehicle. I was given a call saying my vehicle is ready. When I got to the dealership, they tell me they can’t hear any noises and they seemed like they’re not interested in my issue, and showed no concern. I clearly said that I’ve played the video with proof of the noise and I was told that there’s nothing they can do about it (even thought my vehicle is under warranty). I drove out the dealership and clearly heard the noise. I still have an issue unattended to and don’t know what to do. Also, last week when my vehicle was serviced, I was told that my vehicle was going to be washed. So when I picked the vehicle up, it hadn’t been washed. They told me they forgot to wash it! What kind of service is this???!!! I would certainly not recommend Ford CHM Kempster Umgeni to anyone. It seems like customer service is not a priority.
