No Refund from Medical Savings account

My son visited our Medical Practitioner middle October after cutting his food. The doctor has a cash practice, thus we are responsible for payment and have to reclaim from Medical aid.<br> <br> This account has now been submitted to Discover 3 times, and 3 times the claim has been rejected due to wrong codes. After referring the account back to the doctor's practice and receiving a revised account, I submitted and phoned Discovery. After holding on for approx. 15 minutes, I eventually spoke to a Shanice who confirmed that the new claim was received, everything is in order and she will personally phone me back to advise when the claim will be refunded to me. After not receiving the promised call after 24 hours, I locked onto Discovery's website, only to discover that it was rejected for the 3rd time and for the same reason.<br> <br> I have around 24k available in my medical savings account. I can walk into any Clicks or Dischem and by any \over the counter"medicine and get it paid out of my MSA without any problems. Yet if I want to claim for a real medical condition"
