Oppel Mokka Selikane exlusive motors sub division of Botha and Deysel in Vereeniging

Good day

We bought a oppel mokka 1.4 2016 model from selikane exclusive motors wich is a sub division from botha and deysel in vereeniging. The car is using water and keeps on overheating. We informed the garage about the problem and they came to fetch the car on a low bed on the 10th of may 2021 on wednesday the 19th the car was supposed to be brought back to is by the garage had to turn around and go back to their workshop as the engine light came on. On the 20th of May 2021 they brought the car back with the exact same faults it had when they collected it on the 10th of May 2021. The car was overheated as soon as they dropped it of at our residential adres you could immediately smell the heat i opened the bonnet and there was hardly any water in the engine. I asked the garage to do a pressure test on the head to see if there was ny damage to the head becuse of the over heating and that was not even done. I am again waiting for them now to come and fetch the car on a lowbed.

Can you please assist us in this matter.
