Terrible Service

An amount of R1896.00 was debited from my account on the 26.03.2019. I have been trying to get explaination for this from the bank but I am being sent from 5 different people who all cannot assist me instead they were very rude. I spent almost 60 minutes on the phone trying to get this money reversed. This is the 2nd time this thing is happening. Why is nedbank allowing everyone to do as they please in my account. This is frustrating because phoning them is just a waist of time. I regret choosing this ban****
