Standard Bank Vehicle and Assest Finance, had the worst the customer service!

I wish I could give a zero star review. I called in to standard bank vehicle asset finance department to update my banking details 2 weeks before my debit order was due for August. We are now in September and still no debit order has gone off. I called in again to verify that snethemba has updated my banking details and I was told that the debit order was never activated. So the male agent, confirmed my new banking details and that he has activated the debit order, it should take about 2 days, it's now been more than 2 days and still no debit order has gone off. I now received an sms that states the following "Standard Bank:You did not honour the agreed arrangement on your Vehicle and Asset Finance account 0674***. Call us on *** to discuss options". I'm not the one at fault, Standard Bank is and this is highly unacceptable, now because of standard bank's negligence I'm now in arrears. Can this be rectified this moment, I will be expecting a call from standard bank vehicle asset finance department to assist me in this matter. Should this not be resolved I will make my way to the ombudsman
