my acc was debited 3times without my permission

Good day <br> Nedbank 's bad service has affected me for a while now and I have chosen to let it pass but this time around they have gone too far , I made an arrange with the bank which was accepted on to my surprise on the 20th my account was debited 3 times 2 amounts of R3375 and one of R1125 I called what I think is *********** staff at the call centres confirmed by one of their colleagues at one of their branches about the problem and that my other debit orders will not go through if this problem is not resolved they told me it will be done and if its not done they will pay my charges I told one of their idiots that my payment profile will o<br> also be affected this happened on the 20th of May and still its not resolved I have had many encounters with these people and all I want is to have a conversation with one of their senior management to make an arrangement to settle all my accounts with them and take my business somewhere else because they are worse than our government and I am sick of them I am not exaggerating Nedbank's staff just don't know what they are doing its senseless for me mentioning the people I spoke to because most of those people are the same.
