Poor service from claim department of umvuso health medical aid

I am not happy at all with the claim department from umvuso health medical aid really it's frustrating. Last year around August the GP referred me to see the specialist and I did surprisingly this year around March I got the notice from the specialist that my account is still in arrears. I tried to ask help my medical aid to sort it out as they told me the problem was from the GP they used the wrong form to ask for authorisation and I did ask if it is possible to send the correct form and make a payment they did send the form and the Dr filled in the necessary information and send it back to thembut still today they did not make a payment I don't know what to do anymore with this matter and I believe the Dr is been more understanding for long now as they handed me over to the attorneys for the matter I thought I have sorted it out but each consultant when you call and ask they have a story to tell shm.
