Worst Medical aid

To put a star it's just for me to only be able to write my complaint coz Discovery medical aid has changed to a worst medical aid you can choose to be covered on. My son was on school holidays and got sick while not in his Town. I took him to a doctor who is approved on keycare as we had previously used this doctor but we were told our medical aid is rejecting the payment. I was shocked when I was told that discovery doesn't cover out of Gp network. Discovery consultant also told me communication was sent in November to my email, I checked my email and there was no such communication. Now we are taking money out of the budget to pay for doctors fee while we pay medical aid every day. Discovery you are the worst medical aid cover ever you make changes and you don't care to inform your clients.
