Overcharging patients!

I queried why 2 separate bills were charged for a Sunday consultant. R410 cash, and R526,30 on my medical aid. I was informed that the cash amt was for an after hrs fee for a consult done after 1pm. My daughter saw the dr at 11am?? If a practice elects to operate on a Sunday then additional fees should not be charged. I am still waiting for Debbie Proctor to provide feedback, 2 weeks later. Doesn't even bother to reply to emails?? I would appreciate urgent feedback or ill take the next step with this complaint.
