Debits without consent or notification

I took out a personal loan with the Nedbank years ago and found myself self unemployed for a 5 years. I notified Nedbank and their attorneys about the situation I was in all the numerous times that they have called me. I have a Nedbank savings account for about a year and I have been working for a few months. My acc has been debited by Nedbank on different dates with different amounts. I was not notified about this ever. They just debit. I don't even receive statements. Last night I was debited R1780. This is a lot for what I earn. They have no right. I want my money refunded. I am now set back because they get greedy every time they debit my account. This is is insane. I will be closing this account and opening an acc with another bank. I was given the number for the attorney *** but there is no answer.
