Bad service and bad attitude

HI there. Was at the bank on 26/12/2018 at the Heidelberg Mall Branch. I just wanted to update my address on the system and wanted a bank statement. The person at the teller ask me for my id witch I give to him and he typed m id number on the system. He told me I must put down my index finger on the scanner and then asked me for my thump on the scanner. After a lot of trying to get my finger prints to register on the system it was a total lost of time. At that moment I were already 80 minutes in the bank. So I asked the person why cant he accept my id book for proof and his answer was nobody can be trusted and my finger prints must work. So I was very angry and upset because they could do nothing for me. They said I must go to Home Affairs to validate my finger prints. The next day on 27/12/2017 I went to Home Affairs to get my finger prints sorted. I spent Two and a half Hours there just for my finger prints to be updated. They give me a letter to say my prints were updated and I can go back to Nedbank. I went there full of trust later the afternoon with proof of residence and was ready to be helped. They ask me again for id and when I put my fingers on the scanner didnt want to work. So where to now??? They just say they cant do anything for me and that is that. I will be opening a account at another bank next month and leave NEDBAN****
