Bad & Horrible Service

Very bad service. I' m really disappointed and hurt at the same time. I own A Ford Fiesta 2011. On 17 July 2023 I brought my car to this branch as the aircon& heater were not working but the main issue then was the coolant leak. As I was handing over the car to them I explained everything. After their diagnosis they told me that the problem is the cooling system (a leaking radiator) and other components connected to the whole cooling system( thermostat & a certain pipe) was faulty and needs to be replaced. I gave them a go ahead to order a new radiator and other stuff After 2 days they called an told that the head gasket is blown as well and it needs to be replaced. Now their quote was around R30 K. It took them the whole month of August fixing the car and I was struggling to get to work as I am depended on it. I constantly contacted them to find out what causes the delay. Eventually they handed back the car to me. After a day I found out that the heater and aircon are still not working and on top the air was not circulating in the car and took the car back to them and now it took them 2 more weeks. Again on 6 September they handed back the car. I drove it for 2 weeks and now as I drove it shows a coolant sign and now the problem was a boiling coolant. I took back again. Now it's the 3rd week without a car and as I and when I tried to find out what is causing the delay they told that they are still struggling to find out what is causing the problem. Mind you I have paid them already. Their service is really bad😭😭😭😭
