Specialist referral

Its been two weeks of hell with dealing with Medshield, i went to see a dentist about a week ago who referred me to a Specialist to have my impacted wisdom teeth removed as they have been giving me hell and unbearable pain, i called the specialist who informed me that they are a cash only practise, amongst four other specialists who said the very same thing - the procedure costs about R10 000 if not me, i called medshield to advise of this and they refuse to pay the specialist before he performs the procedure and he refuses to do the procedure until he has been paid, so tell me where I'm I going to find +R10 000 in a global pandemic? where I'm I going to find that money so the surgery can be done? everyday I still up at night, I cant eat or drink proper foods because the pain is so unbearable that sometimes my gums bleed and this needs to be attended to ASAP but instead the medical aid that I pay each and every month refuses to help me in my time of need, what im i supposed to do now??
