Unacceptable SPG on Discovery Classic Comp. Medical Aid

I would like to check if anyone else on Discovery Classic Comp. Medical Aid has experienced the same issue as I have. My Self Payment Gap has always been around R2k-R3k. This year it was close to R7k. When I questioned it in the beginning of the year I was told they had received a few complaints and that it was due to a system error which they were working on.

After months of following up I have now been told the agent told me that in error and my SPG is correct, how can they even justify that with the premiums we pay!!

I have also noticed that for hospital admissions where we previous did not have to pay for admission that there is now a co payment due on day of admission.
