Horrible service from Sanlam regarding payment method

I have been with sanlam for many years with same financial advisor. In july I requested my financial advisor if its possible to change my payment method from debit order to stop order. I sighed the documents and shared with her. She then told me that it will cost 300 something rands for stop order. I asked her to not to proceed. During this process one of the Sanlam employees indicated that the forms that I completed did not include correct information hence she could not proceed and process the stop order. Unfortunately someone went ahead and processed the stop issue despite being informed that I no longer need the change of payment method. To the shock of my life sanlam deducted money from my salary via debit order and now they are also going to debit me on my pay day. How is this fair? How am I supposed to survive? Why am I paying double premium?
