Worst Panel-beaters ever!!!

Booked my vehicle (BMW M3) into this place for panel beating. It took 6 months to get my vehicle back. The owner never takes calls and provides dodgy answers whenever contact is made about whats causing the delay. The owner (Sugan), also attempted to add on 25% to quotations from BMW which is illegal, i inquired about this and his response is that he is trying to run a business. I had to start buying spares directly myself. Additionally my petrol and heat gauges were suddenly not working when the car was released. He quoted me a final payment incorrectly and increased this by 3k the day i went to fetch the vehicle. He also decided to add on R600 for fuel, looks like he went for a Joyride to PMB as my car had half a tank of fuel when it got there and when i fixed the fuel gauge it only showed quarter tank. My left rear rim has damage and there was no damage previously.....looks like someone lost control and damaged this. An absolute joke of a panel-beating shop............Don't ever put your vehicle in there. I decided it was just better that my car was out and so i paid and never will never deal with them again.
