Shocking feedback from medical aid

I have been a member of this medical aid since 1986. Over the years I have not had excessive use of the medical aid. I have a loose crown now. I app**** to the Medical aid for financial assistance to replace my crown. After all the paper work, they said that they will give it for consideration. I did not hear from them since June. I phoned them the other day and this it what I was told. It is medical aid rules that prevent them form assisting me in replacing my crown. What a lot of *******. They new this before they told me to apply for special circumstances. They waisted my time and created expectation. This tooth keeps falling out. I went to a dentist to fix it. The account for 10 min work was R3400-00. Shocking!!!!! This was taken from my day to day account and depleted my entire savings. Now the dentist says I need to replace the crown. Another R7100-00. This tooth will cost R10500-00. Me, as a pensioner, can not afford such an amount of money. I need assistance. The dentist says I will either have to pay the money up front, or wait until January for my new benefits. Every time I visit the dentist to cement the tooth the account is more or less R1000-00. I have to pay it myself. If I wait until January it will deplete my entire savings and then I have no savings for 2022. I never expected the medial aid to pay the entire amount. However, they are treating me as if I am abusing the medical aid. I am shocked at the way they are treating a very loyal client.
