Poor service

Very disappointed with service of Orange Toyota in vryburg my vehicle went for radiator repair after 7 days it was leaking i return it, and was diagnosed with water pump leakage after water pump replacement it starts to consume a lot of water i returned it back again, they indicated that the vehicle is overheating due to thermostat installed in the vehicle is not the original part to my surprise i only service my vehicle at Toyota A Warranty officer indicated that Toyota have failed me because they should have check all the cooling system parts after installion Toyota has cause a lot of damage in my vehicle, and they indicated that for them to assist i need to pay an amount of R18000-R30000
