No responsibility or customer service from Medicross or their Dentist

Our son went to see Dr Christiaan at Tokai Medicross and I couldn't be with him as I was at work but his older brother was with him. Our son was told by Dr Christiaan that he couldn't help and that was it. Had to pay R380 for nothing. I appreciate he may not have been able to help but he didn't even offer a dental check-up - just 'kicked him out' and sent him to the accounts department to pay for nothing? I would NEVER recommend it. I have asked for feedback and Medicross said they are not responsible for what the doctors do but have asked him to call me. 3 days later I chased up and still nothing. Medicross seems happy to take bookings and money but customer service is not their top priority.
