Will NEVER encourage anyone to sign up with Discovery

I worked abroad for 4 years and was on medical aid all that time. When I returned to SA last year and re-registered with Discovery, they gave me a waiting period for 12 months because I wasn't insured and because of my existing conditions. I sent Discovery proof of overseas coverage but no they insist I wasn't covered. One discloses existing conditions only to be penalised. Discovery wants to encourage dishonesty. I Will NEVER encourage anyone to sign up with Discovery and I will never have anything positive to say about them.
