Theft for the third month in a row from discovery

Unbelievable. I complained about this last month and they have done the same thing again. I have a medical aid account with discovery and they put me on vitality without my consent , I emailed them the very next day saying it's unacceptable and I want to be off this vitality. Discovery then said they have cancelled my discovery vitality membership however I was still charged an extra R1500+- last month ( a whole month after them saying I'm no longer part of vitality ) I complained on hellopeter and got a swift phone call the next day where they agreed as I showed the emails between discovery and I, that I shouldn't have been debitted that money , they then sent another email confirming that my vitality was cancelled on the 30/08/2021 but this month I only put enough money for my medical aid ( the amount I paid for months before they put me on vitality without consent) plus an extra R15 for debit order fees ( which is R3.50 normally ) and my debit order bounce , the app says my vitality is still activated so yet again I am left dealing with this problem which was "resolved" 2 months ago and then again for the same problem "resolved" last month however here I am stressing and having my debit order bounce so my credit record is going down. How many more times will they tell me that I am not a vitality member before they stop charging me for it.
