really?

I recently resigned from my job and due to this happening. ...I sent a mail to [Email Removed] requesting cancellation of my medical aid but also to ask for my premiums back esp since ive never made use of it nor am I working for the company that required me to take it. I sent the mail last week Wednesday and received NO response whatsoever. Ive been psrt of many medical aids and when I asked for cancellation or for my premiums back I got a response and I got a tax certificate for me to get them back....if you guys are a bunch of *****s just say do mxm
