Discovery Ignorance

I've been a member of Discovery Health for the past 3 years, and this year i changed my policy for claims "not" to be done at Discovery rates. Having made this change, I've since done 3 claims for my wife's Gynae visits and yet Discovery still processes my claims at scheme rates. I've called Discovery countless times and no one seems to care enough to resolve this issue. I'm greatly inconvenienced with Discovery, and all this seems to be constantly swept under the carpet each time.
