LEFT WITHOUT A VEHICLE AND NO UPDATE!!!!!!

We have an extended warranty, however the car is on 75000km. The vehicle was smoking on 7th January, while driving it. We immediately parked it off and dropped off at Toyota Ballito on 8th January for assessment. The vehicle had only just been serviced 3 weeks ago by Toyota Ballito. There was no signal given once the vehicle started overheating. The engine was stripped and sent to engineers. Toyota SA have failed to answer our queries on email and the call centre just refers us back to the dealership. We have no idea what is going on one month later while I'm without a car. Apparently Toyota does not provide courtesy vehicles to the clients.
