Security not good enough!

Yesterday, I went to Spar to buy a few things. When I returned home, I checked my phone and I saw that there were 3 transactions completed in Khayelitsha (2 withdrawals for R1000 and R500 respectively, along with a purchase of R180). I used my card in Middelburg in between the 2 withdrawals made in Khayelitsha. It was all done in the space of 10 minutes. I then call Nedbank's contact centre who proceeded to stop the card. The lady with whom I spoke then tells me it is unlikely that my money will be returned to me if the withdrawals were successful. She eventually transferred me to the ***** department where I was met by an answering machine and left a message. I haven't yet heard from them. I want to the branch here this morning and after a long run around, they called someone who says they'll assist. I'm very perplexed as to why Nedbank has no ***** hotline, why this was not detected and I not alerted and how these transactions appeared on my bank statement yesterday but not today.
