Bad customer service

Good day

I joined Bonitas Medical Aid in October. I was advised that I should eft the premium for the month of October as it is already in the second week of the month then the end of October they will just deduct the premium for November month. I then proceeded and made an eft for October but the end of the month they did a double debit order for October and November even though I eft'd the October premium already. I then phoned them and was advised they obly process refunds after the 7th of each month. On the 6th November I phoned them again and was advised that they received my request and that my query is at the credit department and my money will be refunded in 5 business days. Today the 15th I phoned them again to follow up as there is still no refund in my account. I was then advised that me refund was never escalated to the credit department they will escalate it now and I need to wait another 5 business days for it to be processed. I am so ****ed off as I have been sendjng mails and phoning them since the 26st of October and my problem is still not solved.
