Medshield dissatisfaction

I would like to express my dissatisfaction about how my quiry was handled Medshield medical aid. I submitted a claim which was approved and later was declined. Medshield will always try anything in their power not to pay the claims. My cousin was also told she will be reimbursed when sending a claim after running tests. Her claim was rejected because the test was done at Dischem not lancet lab as if those tests from Dischem won't be going to lancet.
