Bonitas medical fund to make clients aware of co-payments

Bonitas medical fund has mislead me and not informed me and the customer service does not allow me to query the incident. I got authorization for a procedure and I asked numerous times if everything was fine and I would not have problems at Lakeview Hospital. Now 2 months later the bill of R50,000 was short paid R 6,000. My hospital medicine R480 was not paid as I left Wednesday and I was not physically or mentally able to get up until Friday. Had no instruction on procedure. I got an account for recently for R396 for their error in January 2016.
