Card retained because of Nedbanks fault

I was called on the 18th but because I already lost out on my job, I could not answer the phone. I was being sent from pillar to post within the bank, firstly I had to cancel my card (spending time on the phone), then get a number to be assisted - waited for almost 40minutes for my number to be called, when my number was called the consultant was assisting someone else! after waiting for longer than 5minutes I asked the "service champion" why was my number called but there is already a client at the consultant! He gave me a new card which was now priority, nevertheless, I still had to wait for the consultant to finish with the client that she is busy with (which is understandable, but why was my number called!). Later on I tried to send cash to my phone, just to avoid using this stupid cards of them, only to find my limit is set on 0.00 - so I called the call centre, and was cut off! It seems to me that I have overstayed my welcome at Nedbank. My question still remains: how can I conveniently forget the last digit of my pin but the first 4digits I remember???? Because I am still using my American Express card which have the same first 4digits as the Main card that was retained because of a wrong pin.

This is Nedbank Central Pretoria Branch and the last time when my card was retained, it happened at the same branch and on that day I called to set my limit on Send i-mali, but today

Good day, thank you for your intervention, however, I have decided to rather move to another bank before I have to go through this kind of extremely poor service again.
