Nedbank ***** going ahead despite me saying the transactions were *****ulent

Nedbank ***** division picked up a suspected *****ulent transaction on my account - very sharp of them and I was impressed. I confirmed by sms that this was a ***** and received an sms saying that they had declined the transaction and had blocked my card I called *** and was told to call ***, where they gave me a case number. On checking my Money App I discovered that they had not blocked my card, so I did it myself. On 2nd June I received another suspicious transaction report which I confirmed. Later that day I checked my credit card and found four *****ulent transactions had been paid out. These not declined after I had said that they were *****ulent. I called and asked the question and was told that "they had already gone through to the supplier" Who incidentally is listed on Google as a **** . I am suspicious too, as my credit card has been maxed out for over four months, and on the 29th May I transferred money into it, and went onto the Nedbank live chat and asked for my credit limit to be reduced and to stop automatic increases. Had I not done this, there would have been no funds in the account. This needs investigation.
