Doctors claim not resloved

I had called in to change my Secondary doctor, which was done... a few days later I had called in to change my secondary doctor to primary doctor and was advised it would take affect on the 1/4/15. On the 4/4/15 I visited my doctor. Some days later I get my claim notification stating \You need to pay this amount as you have already used your out-of-network visits for the year. Please use your chosen GP from now onwards."I called discovery and spoke to a Jessica who advised me there was a system error and she would process the claim to S Govender again...today I log into my claims history and see its still not paid! this is extremely frustrating as I've taken the necessary steps to sort this problem out. My baby is now sick and i cannot take her to the doctor cause his last claim was not paid!!!"""
