Eugene Marais Hospital Account Disgrace

Utterly disgusted at the way this hospital accounts is handling me at the moment. My son had a shoulder operation in February at Eugene Marais Hospital. April I got a statement from the hospital for an amount of R1 804.03. Upon querying the account from them and my medical aid, it clearly states on my statement MEMBER NOT LIABLE. Since April nobody from the hospital gave me an answer after numerous e-mails. Now, 4 months after the operation, the hospital insist that I pay the amount. Pure thievery. If I am not liable why must I pay? It was pure negligence on the hospital's side to not notify me or the Dr that the equipment he was going to use in theatre, was on the exclusion list that the medical aid send them annually. I am highly disgusted about this whole situation. This was a scheduled operation, so they must have known what will be used in theatre, and notify me and the Dr prior to the operation about this exclusion. It is highly unacceptable that I must pay for something that clearly states MEMBER NOT LIABLE.
