Billed under higher income without my concern

I've been under the Boncap option since 2013 and now this month I have been billed under the highest option without my approval. I've sent all documents & phoned countless times and the person who was assisting me last week confirmed that all my documents have been received and I will be charged under Boncap. I don't understand why I'm supposed to be charged under a cover I don't want & don't afford, this is ***** & a *******. It should be my choice as I am the client & the one who's paying. Now Bonitas has taken half of my salary & I still have other debit orders & commitments, how am I supposed to survive this month then? I will not be under a medical aid that doesn't respect its clients. I want my refund and if Bonitas cannot put me under the cover that I afford then I will move somewhere else. <br> It's busy being advertised as the number one in SA while it robs off people. I am very angry. You cannot take my money without my approval. I even phoned this morning but I was put on hold forever till I hung up. This is unacceptable
