Poor customer service provided by Bonitas Medical Aid

Terrible service. My mom had in-hospital accounts that was not covered in full although ICD-10 codes and authorization numbers was provided. Previously a review was written where Bonitas promised to get back to me and never did. Ons the 31st of March I spoke to Themba from Bonitas after I paid my mom's accounts in cash and Themba promised that Bonitas would be paying the accounts from the in hospital benefits within 20 days and refund us the money. Well it is July and no word back from Bonitas this time again. I will never encourage people to join Bonitas medical aid if this is the type of service that they provide to their clients or family members.
