My claim not being processed

I took my daughter to a network doctor on the 2nd of February and the doctor asked me to pay cash and claim from my medical aid since it was the first time consulting with them. I took the slip and submitted a claim with Fedhealth on the 8th of March, I called them 3 days later to find out if they received the claim and the advised me that it takes 7-10 working days for my claim to be processed. I waited 12 days later and I called again, they told me my claim could not be processed because the claim codes were not on the invoice. No one called or email me to tell me this information, I had to call them! I told the guy I was speaking to that the amount I'm claiming for was for consultation fee, and he said he amended the claim and resubmitted it. Its the 18th of April and I still haven't received my refund, I get charged every month for the Vault but I have to pay every time I go to the doctor, what is the point of all of that?? Fedhealth must just let us know if they don't want members because their service is appalling and disgusting!
