Loyalty cashback payment not paid two months later

I am extremely dissatisfied with the service from Absa Vehicle Finance. I have financed 3 vehicles with Absa and with my recent one was told that I will receive a loyalty cashback. I settled the previous vehicle on the 30th of July but only received a paid up letter on the 12th of August, after a few follow ups. I was then told the account will be closed and the loyalty cashback will be processed. To date I have not received a cent, nor any feedback, despite numerous calls to Absa. Yesterday I was put on hold for over ten minutes and the person hung up on me. I called in again today and I was told the previous account has not been closed, almost two months later! I must now wait for Miriam to process the loyalty cashback. It's absolutely ridiculous how bad your service is. Can this be expedited please
