My Monthly Vehicle Installment Increased TWICE in One Year!

I am extremely disappointed with ABSA, they increased my monthly installments twice which is unacceptable, the increase for last month was by R1100 which is significant. This is extremely disappointing as the car finance is something that I cannot afford now even though I have budgeted for it extensively. The debit order taken last month was by the increase and when I followed up on why they took so much they announced another increase in my monthly installment (I already received a notification of increase last month). I am extremely disappointed with ABSA and their facetiousness.
