Bad services from Discovery health

i have been trying for hours to get a hold of at lease one agent to assist with me canceling my medical aid with DISCOVERY HEALTH but no one seems to give or show any assistance. After realizing that getting any help from agents of customer care itself, i have decided to cancel my policy as their services are over rated and they do not fulfill their promise to their clients. I have tried multiple numbers and multiple departments but no one helps and agents drop my call. This is unprofessional and extremely unhelpful. To discovery if you are reading this if no agent calls back as requested, i will block you from debiting me as no one is helping me and you can take that as cancellation of my policy!
