BAD SERVISE

I am simply tired of discovery medial aid it's always a hustle when one has to claim back from the medical aid. I submitted my invoice and received an email stating that claim will be sorted out between 2 to 3 days. 5 days later I get an email that I need to submit an invoice which I already have. Now the consultant told me that the claim was captured but the funds have not been released, and that i must wait 3 to 5 days. I HAVE AN OPERATION SHEDULED FOR THE 14TH I HONESTLY DONT NEED THIS STREAA AGIN BELIVE YOU ME I WILL BE CHANGING TO MOMENTUM MEDIACAL AID
