I couldn't get of this RMB and my bank didn't not sure if which bank is this, but I I told them what I was experiencing they kept on saying they will come back to me or they are waiting for the response from their management till I got ****** my phone and loose the contact info from their side, but when I called them now they told that they forfeited my whole money that I was busy saving it for my kids and the lady who was helping me she said I won't get it. I hereby seeking your help to this matter, I also wrote a complaint about to nedbank complaints department no response till today. Thank you for your understanding and helping me out in advanced.
