They ****** me off my R900 with my monthly debit

ABSA sent me a monthly statement as they do every month for vehicle repayment, as with every other month the statement filed r November stated that they will deduct R2898,07........ to my shock they deducted R3718,69 ??? what the hell is this! Without letting me know via monthly statement you people decide to rob me off my hard earned R900....... I want my money back into my account! Otherwise I will go to all social media platforms and show the whole country what ******* you are! You can't be sending me a statement to say you will deduct so much and come month end you inconveniencing me by taking more that what the statement stated. I am disgusted by your conduct and how you treat your clients.
