Keyhealth medical aid claim processes are useless

I paid the patient portion of the Specsavers invoice on the day of the appointment, as you can't leave the shop unless any outstanding amount not covered by the medical aid on their system is paid in full. I then submitted the invoice and proof of payment to the medical aid, requesting them to refund me from the savings fund of the medical aid, which has always been used in this manner without any problems. However, a month later it's still an argument. They will now reprocess, pay the full amount to specsavers and then specsavers must refund me....does it make any sense. IF this was how it was always done, then i wouldn't have this as a new problem. Now i'm fighting to get back money that's in a savings fund, that belongs to me anyway for this very purpose.
