Medshield doesnt care for their Clients

So on 31 December 2018 i had to be rushed in to the hospital for an emergency. However due to Medshield changing my medical aid number, i was unable to use the facility which i pay a large amount for. I had to pay everything in cash just so i can do everything i needed. Now Medshield has decided that they cannot pay me back my claims because i didnt get any authorization. What a joke? When you tried calling the call center, both myself, the hospital and the Radiology department tried calling and no response. So i decided to pay the amount for the MRI because i had kidney stones and needed immediate action. Now the medical aid doesnt care, obviously no interest in their clients or their situations because the call center wasnt available now refuse to pay. Stay far away from Medshield. I am planning on changing the medical aid immediately.
