Discovery Health disgusts me

After many many years of huge contributions and hardly a claim, Discovery have used every tool in their rules book, not to pay 2 of my claims in full for dentistry work done on me in Dullstroom. This company also has a large investment of mine which I will terminate with them in 6 months after the 5 year term. I want to warn any future client to look at alternatives as they are no where near when it comes to looking after their long term clients
