ABSA failing customers.

I have been over paying my bond and the additional payments habe not been allocated to the account. I was not supposed to be debited for January due to the over payments. However, ABSA still debited my account and when they have to refund me I have been sent from one department to another. Now they say my bond account has been put on hold. On 2023 they had blacklisted me for no reason and it was also a struggle for them to correct their faults. And no one is taking responsibility.
