ABSA treats black people like second grade citizens

I spoke to an Absa consultant in April or early May regarding my arreas amount that they didn't debit in April. I opted to settle arreas over May and June 2024 with a Debi check mandate that is still quite active on my account. The first installment went off in May as scheduled, and I confirmed with the consultant for 25 May and 25 June for payments.

The payment didn't go off on the 25th of June, the balance then was R3700 and some change. Today, Absa tells me that I owe them R7000. I've taken every call from them, including 3 calls from today, including one where I called back. I'm so sick of Absa's service and the incompetence of their consultants, who you tell to execute something and they don't. Among the 3 calls today, 2 of their consultants put me on hold for a minimum of 10 minutes at a time. They must fetch this car if they don't know how to listen and execute.
