FNB does not help at all

Im trying to close my account but I've been send from pillar to post, I was a a branch and they said that they have send a email. I just called FNB and I am still not helped. The reason for closing is. I am under debt review and there is debit order that are going of that I did not authorized. Every time there is a debit order that goes of I am charged R110. It came to a total of R1100 by now. Im trying to get by debt under control but it does not work. A consultant spoke to me now. but suddenly there is no one on the other side on the line but the call is still ongoing for 16 min now. FNB can stop the debit orders but will charge a extra R25 per debit order. I am frustrated, at this moment I feel like leaving everything and let the account go into the minus and leave it like that
