Worst banking service ever

Worst bank ever. Had a nightmarish experience since the start of opening my son's account. I went to open an account at Nedbank Seapoint for my son and it took the consultant more than 40minutes to complete the application. Apparently I had to open an account and then I needed to link another account to mine as he is a minor. I was informed that both cards will be delivered at the Seapoint branch. I got an sms to pick up the cards. Me and my waited for 1hour 55minutes to be served, just to be informed by a consultant that only my card was available at that branch and my son's card was delivered at the bellville branch. This didn't sit well as the process was already taking forever since application date. I asked to see the manager. I told her how I felt and said that they must cancel the card in Bellville and issue me with a replacement card for him. After receiving these cards I started to deposit money in his account. Surprise surprise a month or so later I wanted to withdraw money at the ATM and was informed that I was exceeding the withdrawal limit even after I tried withdrawing a R20. I went to the Seapoint branch again. After 30 minutes of waiting the consultant informed me that the card from Bellville was still on the system but inactive. The card that I requested for my son previously at that branch was not even showing up. He said he will cancel it and activate the replaced card. But there was another condition, even though there was money in the account the replacement card would not be actived till I made a deposit into that account at the ATM. It would take 48hours for the account to be activated after the deposit. I lost it and informed him several times that I want to close the account. He told me he can't as I had to wait for the account to be activated first then had to come back to close the account. I just gave up , went to the ATM and made a deposit. A week later, I can't withdraw money, the old card is still on the Nedbank money app and there is no sign of the replaced card on the app. This means I have to go back to the bank again. I only feel negativity towards this bank. Patheticly poor service, especially the Seapoint branch. I have never ever experienced this type of service anywhere. I'm so frustrated with them
