Absa VAF team leaders have zero communication skills

I refinanced my car through Absa in November 2022 and was promised a cash back. I called them and they advised that it would take 45 business days for me to receive my money. I then called them last week and was given an amount and advised that I would receive this cash back by Friday 6 Jan. Friday came, no money. I then called them on Monday and was helped by a very friendly lady Antoinette Hlabahblaha, she then advised that they have my incorrect banking details and because of this, the money kept bouncing back. She asked me to email her my current bank statement and a copy of my ID, of which I did. On Tuesday morning I received the following email from Sibongile Mabunda, with Antoinette and the Team leader cc'd in this email: "Good morning Antoinette Kindly be advice that the Rebate is not approved by my Team Leader Geneve , so I wont assign it due to not approved. NB Call will be closed" I immediately responded to the email requesting a call back as I wanted to know why this cash back which was promised has now not been approved. No response. I then emailed Geneve Marillier(the team leader) directly and have still not received a response. ABSA IS THIS HOW YOU TREAT YOUR CUSTOMERS? I would give you zero stars if I could.
