Their service is not people centered while they provide cars to people

I started my rent to own application on the 22nd of March and selected a car from one Planet42 registerd dealerships, paid R30000 deposit and I was called to come pick the car on the 12 of April. I got to the dealership and I was told they can't deliver the car because the car wasn't fitted with Tracker, but how come the dealership call me to come pick the car while not everything was sorted. Even today I'm still waiting for the car. I have sent emails to dealership support department and still no response.
