********* financial retrieval of debit orders even after cancellation of policies

I cancelled my PPS, going through all the correct routes in October 2018, yet to my dismay, still every month a payment of R1300 IS DEDUCTED, even after all the legal documentation to cancel was signed and sent through by my broker, and after a personally cancelled the debit order at the bank! December again a payment was taken via debit order!! I took time off from work, and manually cancelled my debit order on 30 January 2019. To my utmost dismay I received an email today that they will deduct via debit order the amount that was missed - on the 6th of February, a debit order which I personally cancelled ,they were seemingly unaware of the cancelled policies. I phoned the email agent, and he promised to look into this matter and that the deduction will not go off. HOWEVER I just received a sms from my bank that they AGAIN took another payment off my account, on the 4th of February!! This counts as *****, violation of my financial affairs and poor ethical business PPS.
