No Response - after numerous emails and promised 48h reply NOTHING FOR WEEKS

I have joined Discovery Health Smart Classic in May 2017 after searching online for a provider and plan. The representative that rep**** suggested Smart Classic as the only option, focused on "cheap" doctor visits, "free dental", overall "a very affordable" but "comprehensive " plan. After a dental issue I discovered the so called "dental cover" to be a **** - only one "check up" per year, nothing else included. I had to undergo a root canal treatment, and was left with a R3 200-00 bill, an embarrassing Acknowledgement of Debt signed in the entrance lobby in front of other visitors, and feeling cheated. Upon further research after this dental "cover" discovery, I was overwhelmed to find that Smart Classic is only supported at a few selected hospitals, and when I inquired online, found the official list on DH website to only have TWO hospitals in the whole of SA where I can receive treatment if needed, both hospitals in the Eastern Cape??!! I have a screen shot of this. I also found that should I elect another facility, I had to make a co-payment on admission of R8 200-00!!?? Numerous emails have been sent, I have made phone calls and I was promised THREE WEEKS AGO to be contacted within "48 hours" as an "investigation" was underway???!!! I have reference numbers, and the said emails as proof of timeline and confirmation that my health and medical care is NOT THE FOCUS OF DISCOVERY HEALTH. I am not impressed that I was purposely pushed into this decision to join Smart Classic, and I am now bul**** with policies and corporation ************: you CANNOT change a plan during the year, you CANNOT use any facility, etc. The marketing angle and emphasis was put on "free dental, cheap GP visits, affordability and comprehensive cover", but never the exorbitant amount of R8 200-00 co-payment and just a few medical facilities to choose from. I understand business, and believe the 'design' of the Smart Classic Plan to be misleading, where consumers are lead to believe their needs are respected and catered for. I have made my side very clear telephonically and via email, now I am ignored and forgotten??!! Do I really want to trust a corporate monster like this with my family's health?? I am appalled!!
