Complain against dealership

It came to my attention that i was sold a car that is a defective vehicle. When I inspected the car I configured that the car is not in a drivable state, it’s a high risk car for me. The seller did not disclose the correct vehicle model and a variant description and mileage of the car, he mentioned the car was a 2014 instead of 2013, never mention the kilometers of the car, I got to realize on delivery that the kilos where 168 000km, which any sales person needs to mention when selling a car to a client,, the car doesn’t have a spare key, no service book, brake pads are damaged even after they claimed to have installed new ones, also they did not bring the car so I test drive it until it was delivered.

I went to the dealership last week friday(05-02-2021) to cancel as i was well withing the days of cancelling. Every consumer has a right to cancel. but i was told that feedback will be provided to me by close of business that day. today it is tuesday Grant from the dealership is not answering my calls. I am not happy with the service
