Disappointed in Absa

Banking with Absa is the biggest mistake on can make. On the 21st Jan i called the contact centre to cancel a debit order, the consultant on the line was not very helpful or friendly. I eventually went on the Absa app and suspended the debit order but on the 22nd January the debit order still went off from my account. How does this work? What is the suspend option for if it actually does not work and does not suspend questionable debit orders?
