worst medical aid Discovery health

My son is a member of Discovery health . His daughter just turned one and now has to have a small navel hernia. It was present at birth but the dr said it can go away or when she gets older she might have a operation but it is not necessary now and they won't do an operation until turns one.It got worse and they went to see a pediatrician and his recommendation was that they see a surgeon . They went to a surgeon and he advised them to have the op. Now Discovery claims that they were aware of this and that they will not pay for this operation because it was a pre existing condition. I have a lot of staff that are complaining about Discovery. They are a **** medical aid. They want your money very quickly but don't pay as quickly as they get it. Pathetic bunch No wonder the state wants to bring in the NHI. Never thought I would say it but we can not be worse off than we are with Discovery Health.
