How ********** is nedbank service???

I reported my card to be ****** some time in July. I then app**** for a new card on the very same day. The new card came and I successfully used it. I tried using my card at woolworths at the airport however it didnt allow me, but i overlooked that as i thought that i spent more money than i had. Until such time I received a message in August to say that there was ********** activity on my card. I then made an effort to make a call and find out what was going on but the call was a bit disturbing as, the old card number was quoted. I told the consultant that I had a different card number and explained that I had reported a card and the rest of the story. At that point I established that the ********** activity occurred on the old card that was reported as ****** and was supposed to be blocked. Yesterday I tried using the card and the card did not work so I went into the branch to find out what was the problem but the consultant didn't pick up anything. This morning I received a call from the nedbank collections department to say that I am owing what ever amount of money and that my account was over drawn. I then asked the consultant how their systems work as these people are using a card that I personally blocked but he said I should go in the branch and give the case number. When I went into the branch still I did not receive much assistance. When I asked the lady how this might have happened she claimed that the money spent on my old card was unauthorized amounts. However the value is too much over 10k unauthorized. I went into the airport branch for further assistance after work and sat there for almost an hour waiting for Jabu to assist me however that too did not happen. He was in a rush to go home. I am truly dissatisfied with nedbank as a whole and disappointed at the ORT Airport stuff members and their work ethic.
