Daylight Robbery - Valet Service

I paid R450 directly to Rainbow Airport Parking to have my car valeted during my travelling. They returned my car to the airport on the evening of 23 March 2021. The next morning upon inspection in daylight, my car has barely been cleaned, with new stains on my ceiling. I have sent pictures to Leon and was told that this would be addressed. I have requested a refund and provided my banking details. He shifted blame to a car wash they make use of and never got back to me.
