AVBOB disappointing customer service

My name is Mrs Molepo and I am disappointed with Avbob as I have been to their branch in Themba(Hammanskraal) to cancel a debit order with them in December 2019 and followed all procedures they requested from me to follow and the Consultant there assured me it will be cancelled and would no longer appear. But it has been deducting my R562.60 from Jan 2020 to date and that is more than R2000 thus far that I have lost due to *********** services and I want my money because according to me I have terminated services with Avbob in December of 2019. I want this sorted and I want my money. My ref with them is AL***X0. cell: ***.
