After Radiator fitment the vehicle still had coolant fault and fog lights not working

I was charged R2300 to install my radiator. When i start my car the next morning i have a alarm saying switch engine off no coolant. When i checked to see if all my lights was working and found one fog light not working. The technician didn't make sure if all airlocks were out of the system or if all the lights worked. I used my own scanning tool to monitor the temperature management system in my car. I reported the issues apart of them not wanting to take responsibility for bad workmanship. I was told the technician will be coming that day. Its now day 3 and still no call or msg to say what the delay is. These people are ridiculous expensive and poor quality of work. I surely wont use them again and definitely wont refer anyone to them
