No Customer Care or Follow through

2 Years ago, I contacted Discovery to get a recommended Maxillo-Facial and Oral Surgeon to get my wisdom teeth removed. I then had to undergo surgery in a different area of my body to avoid cancer in infected tissue in the beginning of last year. The surgery missed some tissue which lead to me having a repeated surgery a year later almost to the day. This was at no fault of anyone. I just turned 21 and have been told to now go on my own medical aid. The only option I can afford at the moment is the Key Care Plus Plan. However Discovery wants to now put me on a waiting period of 6 months because of the surgery, yet i have been with them since the day i was born. Discovery has now turned around saying they won't cover my Wisdom teeth what so ever, yet I have been waiting 2 years to hear back from them. If they had contacted me earlier, like the stated 1 working day. My teeth would be sorted, I would not be in pain, and now not being able to afford the removal. I cannot eat properly most days and I have sent more than 1 query and all have been swept under the rug. I sent an email a week ago and still haven't received a proper REPLY, just 10 word emails.
