DISCOVERY and their poor CS

I have recently moved by medical aid into my personal capacity yet I have received 2 emails in 2 months regarding suspension. I am also trying to get a hold of the help desk via mail yet no one responds to me. In addition, they are double debiting me and I am not too sure why as I have sent through PoP of the previous month. It would really be great if someone could get back to me URGENTLY VIA MAIL please.
