Nedbank poor service

Being to Nedbank Kenworth branch in Bloemfontein 3 times as I was struggling with Nedbank money app but could not get help . Was once told I can’t add beneficiaries on my add but will have to walk into the bank for them to add beneficiaries for me and then on my third visit I was told again that I can add beneficiaries myself and got helped to add beneficiaries but they couldn’t until they added them on their system. And then something happened, was told to log on to my app so I can make a payment that I so wanted to make,I logged on and there was my beneficiary and the pay button, I pressed it and the next step was “finish” with no option to go back, I then told the lady I am not ready to make that payment for I needed to make an instant payment and the app didn’t ask me for that I then tried to log the screen away (iPhone) without pressing finish but the payment went through instead and was told I can’t reverse that and if I want it done I must be ready to pay 400 bucks
