Integra Motor Group - Bunch of *****s! Never buy or sell you car here!

I left my car with Integra as I was going to be out of the country for a lengthy period and was looking for someone to sell my car. I left my car there, agreed on a price and left the country. 2 weeks later I inquired about the car and was told that the car is sold. They however told me that the car was sold for much less than the asking price and that they would give me about R20,000 less than the price I asked. I told them that I agreed to this if they could show me proof of the sale price. They refused this request and from there most of my requests, emails and whatsapps were simply ignored. Today I had to get my brother back home to make contact as they were simply ignoring me. He eventually got hold of them and was told that the car has been sold. Nothing I can do about this. The car is sold for a price that I did not agree upon. Through this I was treated like absolute ****.
