VERY BAD/ GREADY MEDICAL AID (POLMED)

I am writing this complaint to anyone who can assist. I am a single parent who is really struggling to raise my kids and have managed to have them covered o medical aid for years without complaint. I have visited my HR office and was told that since 2020 my premium have drastically changed from +-R600 to +-R1600 and surprisingly jst jump to +- R4000 in April 2021. I then tried to use whats to get clarity from Polmed but could not get the OTP and then ultimately got stuck without talking to consultant. I called then the consultant told me I did not send proof that my kids are still at school and usually I would hear people saying their kids are blocked/ terminated from using medical aid funds but with my case I got a surprise that I owe Polmed. I then sent the form termiation of dependants because I really cannot afford this and what is bad even more Polmed doesnt try other avenues to get hold of members when there is an issue. I really need urgent attention to this matter as I dont even have transport money now in this bad time in South African where economy has dropped and how should I survive this month if I am treated like this. Polmed jst take whatever amount they wish to take without proper consultation. Yhooooo if I had other option I was going to cut ties with Polmed.
