"How can we help you" not at all!!!!!!

I have been placed under Debt review and as a result all debit orders on my account at FNB have been cancelled. However 3 debit orders still went off at the end of February 2020. I have been trying to log a dispute for the reversal of these funds into my account but to no avail. The Call centre is useless and logging it on the app was also pointless.I have even sent emails but with no luck. How does one bank with a bank who has the logo "How can we help you" when they clearly don't want to. Have had my account for a long time but am starting to rethink my choice now.
