Nedbank incompetence

Nedbank really knows how to inconvenience people. I'm really ****ed. Today I wanted to increase my limit on App and failed to as there was an error message popping up stating that "card limit error", spoke to an agent on the app and was told to call customer care. Customer care said they couldn't pick up any card on my name because the card that I'm using was canceled or freezed as I was issued with a wrong card and should go to the branch to pick up a new card that I'm supposed to use. My plans had to change because of nedbank incompetence, have been on the queue for 2 hrs and still counting. I believe the best option is to cut all ties with them so that I can have some piece on mind. Have been using my card for over a year surely they should have picked this up a long time ago and even last month I was at the branch and I should have been informed about this.
