Pathetic service from Bonitas Medical Aid

I am have been a loyal Bonitas member for 10 years now and never had issues, however yesterday I went to my specialist only to be told he had been kicked of the Bonitas network and had to pay cash for the consultation fees. The scheme did not bother to communicate that information to me since 2021. Furthermore I have been informed that for any procedure with the same specialist there will be a core payment and the scheme is not covering him in full anymore. I have called the Scheme's customer care and requested to speak to their escalations manager for further clarification and explanation why the scheme never bothered to inform me but no-one was willing to speak to me. I am totally disappointed from the service I have received from this insurance and will not recommend anyone to join this service provider. I am now in the process of terminating my membership with them.
