Checkers 60 min bikers speed dangerously

Good day, I fear for my life and property every time I park my car in the ba*****t parking at Jean Village shopping centre Checkers. The 60 min bike-drivers speed and have absolutely no regard for life and property. I have complained numerous time to the management with no results. I know we live SA where the customer is last on the list, but I am actually a paying customer if it means something. I am going to take this further and make a call to the police, if nothing is done. Sorry also does not mean much anymore. It is time you do something about this.This is probably going to be yet another 0 on a contract.
