Kia Silverton:Car damaged after service

I sent my grandson and his father to Kia Silverton on 17.02.2020.My Kia Cerato was due for a yearly service. On arrival health check was done on the car(proof on invoice), no damages detected. According to the people sent the car was just handed to them around 16h00. They reached my work place around 17h00(Laudiam). Arriving home i realized that the bonnet is extremely hot. I opened it to cool down.Was even thinking the Coolent is maybe finished. As a woman I didn't know what it was. In the morning my son inlaw came checked the car and noticed that the fan was not functioning thus the over heating.He then advise me to drive with the air conditioner on as that makes the fan kicks. I then called Kia Silverton and spoke with Ms Bester who was not convinced im telling the truth. She later that day sent a whatsapp which requested my work adress. She said a technician will be sent. Indeed John did come, after working on the car the fan was functional again. I showed him the damaged R light which was also reported to Ms Bester he suggested i report to management. On 25.02 2020 an email was sent to the service manager Marius, no response. On 28.02 2020 i called Kia Silverton and asked for Marius.He told me there is nothing he can do and he can't help me. I'm really disappointed cause its the first time taking my car to Kia Silverton. For the past five years my car was serviced at Kia Fountains and I'VE NEVER EXPERIENCED ANY CHALLENGES/PROBLEMS. Today 03.03.2020 i washed my car and noticed both wheel macs damaged. Im so stressed up i wish i didn't take this car to Kia Silverton. Paying close to R4000 for a car to be s****ped off its parts is really
