lacking old school common sence

I joined Bonitas January 2017 of which they had to debit my account. In February I had to call them because they did not debit my account for January. I made payment and they started debiting me beginning March for February or at lease I though. Many months later they wanted to debit my account twice with out informing me or requesting a second payment. The second payment failed because of insufficient funds and the bank charged me R100 bank charges. I put in a claim for reimbur*****t for the charges and why they tried to debit my account twice. They rep**** that my medical aid is suspended until an installment is received because I am suppose to be an advance paying client. I made payment because i need my medical aid and requested that they refund my R100 and they rep**** that they don't do refunds. The bad thing is that they could not call me for payment and all correspondence with them is only through email because the call center does not deal with such issues. Thumbs down to customer service.
