Terrible,Pathetic Customer Service and unacceptable behavior

Nedbank is worst, pathetic bank ever. From their call centre's to. They're all very unprofessional. My brother was fiancée by MFC and Nedbank. At some point he was on debt review however he's no longer on debt review. He received a letter confirming that he's no longer on debt review from Nedbank and even other service providers have given him credit accounts meaning that even all credit bureaus have removed his name as a person who's on debt review however when he calls Nedbank Debt review department on Tuesda the 1st September he came across a very rude lady in my presence who told him he's still on debt review from even though she saw a court order which was sent to both MFC and Nedbank, she also confirmed that she saw the letter which was sent to him by Nedbank confirming that they have updated their records, this lady continued arguing on the phone on what the court and the magistrate should have done on the court order. She then hung up on him. He called the same department and asked to speak to the supervisor to report the lady who hung up we were told by another contact centre agent that they can't trace call nor do the write note on the system, we then proceeded to ask her what's the use of telling us the calls are being recorded if they're can't trace people who render bad service and we asked to speak to the Supervisor within the same debt review department , a lady bybthe name of Zanele confirmed she's a supervisor promised to resolve the matter, apologized on behalf of her colleague who hung up on us. She promised she would investigate the matter, tace who hung up and resolve the debt review issue. She promised she would call us bck the very same day but we haven't received a call to date. We called the same department, we held on got through to Nedbank Customer Service and got through Thato who couldn't help but instead transferred from Pillar to post. We spoke to another agent from the debt review or collections department and got through to a lady by the name of Khanyisa who asked for him to explain himself, we narrated the story but we insisted we wanted to speak to the Supervisor Zanele or a Manager on duty but instead she failed to do that and she refused to give us her fullnames and Surname. She told us that she's uncomfortable giving clients her Surname and as we continued asking to speak to a manager she also hung up. Where's Customer service at Nedbank and MFC don't they have Q A sessions because they do as they please and go as far as dropping calls on clients. Should Nedbank not update nor resolve my brother's query within 72hours we will take the matter up with the National Ombud Scheme. I would like all the ladies be traced and brought to book, Nedbank is not a ****a Shop but they're now operating like a fly by night bank with no discipline and Customer service.Those Call Centre Agents are tarnishing Nedbank and MFC brand. How is it that these mean call center agent are untracable when the call are being recorded?
