COVID NEGATIVE TEST NOT PAID CLAIM

I had a covid test done on the 10/06/2021 still not paid till today.I have sent the relevant info to the healthcare 1st one they said they cant open the attachment i have to resend which I did Ref 481340265.I was told that the medical aid doesn't pay for negative results of covid .I was sick and had all signs hence the dr said I must go and get tested at lacent.I didn't know the medical aid didn't cover it I was told the day i asked why its not paid. I feel its unfair they don't cover for negative test .I am now sitting with a bill of R850 that i didn't budget for in a medical aid I am paying every month.
