NMG Benefit very unreliable and disappointing

I'm so shocked on how these private sectors that we had made believe that are better are actually so ***********.You cant have someone as client and don't bother give the service.NMG benefit is not only unreliable but very frustrating,they don't acknowlegde,or respond to emails,nobody is making a follow up on enquiry very unprofessional.January 2023 I put a query with them to assist asap on my medical aid issue as I'm being handed over to debt collectors,and tried following up few times,they are always escalating, to this day no one has ever contacted me...
