Absa *******ly debits from my account with zero apology

Despite not having a homeloan, Absa continues to debit me month after month. I've sent several letters and complained on social media and I have yet to receive a formal response via a stamped bank letter from a GM stating that I will no longer be debited. They have also refused to refund me the full amount that they effectively stole from me. I am cancelling all my interactions with Absa, I've been with Absa for over 35 years and this is how they treat their customers!
