BAD CUSTOMER SERVICE!!!

When I joined Fed health at first I was so excited about they service was so quick and effective, I even convinced 4 of my colleagues to sign up and now this year they disappoint me so much the time when I needed them the most. They gave me R12 900 in my Medivault for 2021 I've used plus minus R3000 which is stated on my savings statement in detail for what I have used it for. And now the problem is on my statement there is an amount of R6700 that they say I've used I've tried for 3 months now by calling, send emails but, NO RESPONSE at all. They just say Simphiwe will send the statement but, no statement yet. And if have used the R6700 why is not stipulated to what have used it for like the others something is not right. On my statement is called a current payment. My child is sick and I can't take him to the doctor this is so frustrating! Fed health have no customer service they don't even try to accommodate me as a client!
