Money withdrawn and cards blocked with out my consent and authorization, not to mention behind my bac****

I App**** for a fast early release of funds from one of my investments, to which I received correctly. With this, I also received an additional R 20 000,00 from an investment that I didn't know. I knowingly took this and placed it in a separate account as this isn't mine, and I am not prepared to take responsibility for this if it was to be used. ( Transferred it to be kept safe and till Nedbank contacts me to rectify).

I was quite busy and couldn't get to the branch to sort this out, and till I tried to use one of my other cards, to which it was declined. I called the contact center and they had told me that my card has been listed as ****** and my new card was ordered. (Without me knowing anything about this).

I mentioned the extra amount that had been debited into my account 2 days prior and was told it had been taken out of my account and would be returned upon further investigation. I accept this is not my money and that I don't want it back. The point I am trying to make is that they took funds out of my account without my consent and authorization. And after this, listed my card as ****** and ordered me a new one, to which I would most probably carry the fee as these cards that they blocked weren't even a week old yet.

My personal banker does not have anything to do with this as she is located in another branch. And was unaware of this completely.

I would like answers and a resolution to this situation as a personal apology will not be enough.
