The ATM swallowed my card

On the 01/03/15 around 14:00pm I tried to withdraw cash from the ATM in Rosebank mall (second floor). The ATM swallowed my card and also another card was swallowed by the adjacent Nedbank ATM at the same moment. However, people behind me in the queue could withdraw cash with no problems. I contacted the emergency number of the bank and they instructed me to wait until Monday Morning, as it was after hours and nobody could help me at the time. My card is a Kenyan Barclays Visa debit card. I tried contacting the bank in Kenya many times to block my card, but was unsuccessful. On Monday morning, I went to the bank but the card had disappeared and 2500 USD was missing from the account when I was able to finally block my card. I urgently need that money which is the reason why I claimed this back from the bank.
