Bank details not updated

On the 11th January 2016, I requested for my bank details to be changed. My reference no CE***. The debit order was suposed to be deducted on the 20th January 2016. I called the call centre today and spoke to Kauthar, who advised that my bank details was not updated and the debit order was deducted from my previous bank account which obviously has no money and it will only refelect after \9working days". I will not be held liable to pay bank charges for unpaids as this was not my error. I'm also not going to waste my time at Old Mutual Parow branch as you wait until forever to be assisted espescially if it's policy related queries. """
