Medical Aid Refund Just Not Happening

I have an unresolved issue with Discovery regarding a claim that was made in July 2019. Several emails, uploads, phone calls, and acting on Discovery instruction, my issue remains unresolved. Empty promises to give me feedback and unanswered emails seem to be the norm. Phone calls keep costing me money. Visits to the pharmacies, sending ever changing requirements of documentation. New reference numbers given to the same enquiry. Explaining my enquiry to every new consultant that I reach has become just too much to bear. I am at my wit's end and most despondent with this atrocious service and non-compliance from Discovery Health.
