POOR SERVICE AND FAILURE TO DELIVER ON SERVICE WARRANTY

I PURCHASED MY TOYOTA DOUBLE CAB AND GOT SERVICED REGULARLY. FROM TIME TO TIME MY SERVICES WERE EITHER INADEQUATE OR DELAYED DUE TO UNAVAILABILITY OF SPARES. I TOOK THE VEHICLE FOR SERVICE AT THE BEGINNING OF DECEMBER 2018 AND IT WAS SERVICED FOR R10 800. BUT WHEN I CAME TO COLLECT IT THEY TOLD ME THAT THEY FOUND THAY EITHER THE ENGINE HAD PACKED UP OR THE RADIATOR CAP WAS NOT PROPERLY SEALING. DUE TO SPARES DIFFICULTIES THEY DID NOT HAVE A SPARE FOR A RADIATOR CAP. ON FURTHER CHECKING THEY TOLD ME THAT THE ENGINE MAY HAVE OVER HEATED IN THE PAST. THE ENGINE HAD EVEN WARPED BUT WITHOUT SIGNS AND DURING THEIR INSPECTIONS AND SERVICING THEY COULD NOT PICK IT UP. TOYOTA IS USING OUTDATED TECHNOLOGY TO INSPECT THE VEHICLES WHICH CANNOT PICK UP ENGINE PROBLEMS. THEY PROMISE 12 MONTHS WARANTY ON PARTS AND WORKMANSHIP. BUT WHEN THE FAILURE WAS DETECTED THEY CONVENIENTLY BLAME IT ON THE RADIATOR REPLACEMENT WHICH TOOK PLACE 3 YEARS AGO. HOWEVER THEY ARE FAILING TO ACKNOWLEDGE THAT THEY ALSO HAD TO REPLACE A THERMOSTAT AND A RADIATOR CAP IN THE PAST. I USUALLY SERVE THE VEHICLE ON AVERAGE EVERY 3 MONTHS AND THEREFORE THE WARRANTY ROLLS OVER AND OVER.
