SO DISSAPOINTED

I called yesterday regarding my bank charges and there was an amount of R150 and few cents which is going off on my account as "Other Charges" I asked Nobuhle who was assisting me, she concluded that she is not sure of what that amount is for. We spent like over 30min on call, she hold me up then came back and said I dont know hoever I will find out and get back to you. Since yesterday I have been waiting for Nedbank regarding that amount, still waiting for their call , still not calling, How is that a business which is runned with promised but still you have to wait none stop. These banks are something else. This Nedbank call centre is not in good standing and its agent dont know nothing cant even answer a simple question.
