pathetic service from national medical aid

Ever since Discovery had taken over administration from Bankmed, the company has severely dropped their service levels and company ethics. Apart from requesting a letter of support for a severe dental procedure that my 7 yr old son had to go for where they received incomplete supporting documents and waited for me to call then to find out, I had paid the dentist up front and then submitted a claim to bankmed. They then paid me R39 from a R613 bill stating that I owe the scheme. What ******* is this. I have the highest plan and pay R6200 a month for medical aid. When I called in to the call centre, they did not know what the heck was going on. The guy Jerome said he would refer to management and get back to me by close of business. Its now 8pm and I still have no feedback. I have to constantly call in for feedback and to query issues. They said there was a claim in January for medication where they app**** a claw payment. What the hell does that have to do with a dental claim which I paid for cash 3 months later? Claw payments are only applicable if a service provider is over paid. The claim in Jan was settled at only 50% anyway. I paid the rest out of pocket. This is horse ****.
