CARD SKIMMING

Not happy with Nedbank service of their ***** Prevention & Investigation. My card was skimmed and used 3 times before I noticed it. The amount was very small the first time and the second and third was larger. Noticed it over the weekend that some of my money was not there. On Monday the transactions still did not show on my bank account - but Tuesday morning I could see the transactions. Went to the bank and reported it - now they say they are not responsible, the card was used in the same area (Richardsbay (Kwazulu Natal) and Oudsthoorn (Cape)), then they accuse me of knowing the person that did this, the disputed transaction's does not fit the Modus Operandi of Card Skimming - HELLO how can the card not be skimmed if the same card was used in Richards Bay (Kwazulu Natal) and Oudshoorn (Cape Town) on the SAME DAY?
