Claims not being processed

I have changed from Bonstart to Boncore and now ever since I have changed to Boncore I have been having issues with my claims not being processed and when the pharmacy claims the message is that the member is not on the Bonitas network.the pharmacy is claiming on the correct option Boncore but the reason is still the same that the member is not on the Bonitas network.call centre agents don't know what to tell you so they tell you different things.im really thinking of cancelling this medical aid and moving to fedhealth.
