Worst customer service

Early August I called for a quote and spoke to a lady, she explained everything on that call and she said she will send an email with the information of the medical aid I signed up for. They started calling everyday and I explained to everyone that contacted me that I haven’t received the email they said they will said, after the call all the agent promised to come back with feedback but nothing came. Few weeks past, they called again and I asked to cancel the cover and they agreed that they will cancel but they didn’t. On Thursday last week, I got sms that they will debit whereas I have been waiting for that email. Today they debited my money, I want a refund nowww!!!!!!!!!
