My Toyota 2014 Rav4's entertainment system has stopped working (I heard this is a common issue with may Rav4s) and it was confirmed by a different dealership that needs to be replaced. I called to book an appointment with Don Valley North Toyota and I got an appointment for the next day. I wanted to make sure they have replacement parts ready before going for my appointment, so I called back to confirm whether they have replacement parts. But the people in the dealership try to send me back and forth between service department and parts department. People in the parts department are very rude, one gentleman said I don't even have an appointment scheduled but the Alby from service department had given me an appointment earlier. This dealership looks like a total chaos and there is lack of co-ordination between departments and lack of respect for customers, who eventually pay their salaries. I would stay away from this dealership and not recommend to anyone. If I have negative rating, I would have given it.
