money taken from my credit car without permission

on the 05-02-2016 I brought back a vehicle BMW on call hired for me to Auto Alphina BMW Boksburg left the key with Megan an employee at BMW. I called Rihan *** some black guy answered the phone. I told him to come and fetch the vehicle. on 08-02-2016 I get a call from Woodford asking me where the vehicle is. told them I left it at Auto alphina. I get a shock the driver that went to fetch the vehicle says the car has a scratch. I never scratched the car. I cant be held liable for a scratch I don't know. I requested camera footage from BMW they don't have apparently.no one checked the car when I dropped it off. they made me sign a form that was incomplete there was no vehicle description no registration. on the 13-02-2016 R1000 is taken from my account. and another R1000 now as we speak I cant access my finds on my credit card because there is R2653 waiting to come off of my credit card. I am not happy at all with Woodford's business. I never scratched their vehicle. making me sign an incomplete form is *****. taking money from my credit card without my permission is *****. I want my money back. no communication. this is ***** is not a way to run a business, im not impressed.
