Bad Service

I took out medical aid from Bonita's in mid December 2015, my first debit according to them was going to be 01/01/2016. The debit order did not go off, I then called in on the 04/01/206 to ask wen my debit is going off. The lady I spoke to said my debit order was not loaded I should make an EFT, as they don't make special debits. Same day I called again to say am struggling with it,can they please make a special debit she refused. Called again 3rd attempt I got through to a guy who did not understand wat EFT is he put me through to the website department. On 06/01/2016 I called the lady gave me Nedbank details my EFT went through successful. On the 08/01/2016 Bonita's debited my account, which caused me to have unpaid debit. I called on the 11/01/2016 got through to a lady called Angie she said I must send her my bank statement of which I did. She called me to tell me that finance can't read my statement. This morning I call her and requested to her manager she told me she is going for a meeting, no sense of urgency whatsoever. Please help as I can't pay for unpaid debit that was made by Bonita's
