Capitec fails to adhere to payment arrangement made

I have been a capitec client since 2012, they don't even deserve a one star. i am so disgusted with they customer service it's pathetic. I have a capitec account and i received a call for a payment arrangement i explained i am not employed currently and i have funds coming into my account and they advised me to make an arrangement nonetheless i had the arrangement go out early jan as arranged with them thereafter they kept deducting money from my account i had to continously call them and they stated that they know about the payment arrangement so they will reverse the funds into my account. Which they did. So i had more funds go in today mind you the debit order date is scheduled for the last day of the month until the 10th today is the 29th they deducted more than the installment and they state they cant reverse the funds. Absolutely pathetic how you make an arrangement with the bank and they do not adhere to their statements made. I had to call them continuously for this and they staff have so much of attitude over the phone. It's sad so please if you do bank with capitec take note of the incident occured they make an arrangement and go beyond that poor client satisfaction they need to go back to their drawing board.
