Dischem covid 19 results ripp off

Last week Friday i went for a covid 19 test , because we have been in contact with my mother that was tested positive, i thought let my go to dischem, they might use one the private labs since to test cost R850. I have all the symptoms for covid 19 they sent my results back to tell me iam negative. I think its a total ******* and they use the same labs as the government use.
