African Bank was negligent and refused to refund me

I was ****** at Makro store and a few minutes after I called African Bank asking them to block my card. The person I was speaking to assured me that they blocked the card and I can block my profile online were I can also see my balance since my phone was also taken. I asked her 2 or 3 times if she blocked it and she assured me that she did. Next day when I got to the branch I found out that my card was not blocked. The consultant who was helping tracking the time I called the bank and when the money (R30 000) was ****** it could have been reversed if she did block the card. On my statement it clearly stated that the transaction was to be processed the following day. This is all bank negligence. I then went to the banking ombudsman and they ruled in their favour. African bank declined my ***** claim.
