Damage after schedule service

I took my Chevrolet Cruze 2013 2..D LS to Reeds N1 City for is 65000 annual service. When I when to pick up my vehicle. I did not bother to check if all was in order as I assumed as Reeds is a professional company with a good reputation, I would not need to. However a few days later, I noticed the service and engine lights was on. I took it back to Reeds, who took it into the workshop and reset the lights. the very next day the lights came back on. I was informed to book my car into the workshop. Which i did.The vehicle started to overheat. I check the water in the radiator only to discover there was no water in the radiator bottle. I filled it up. When I did take it into the workshop, they discovered the radiator water had drained out. I have now been told the vehicle needs to stay in the shop over the weekend and maybe as the part they need will arrived in the next week. I am further been told they do not have a courteous car and I am going to have to pay R 1500.00 myself to hire a vehicle.When my vehicle was in the the scheduled service. I was only told of a park light that was not working. I was never informed of any other repairs which needed to be addressed. <br>
