Nedbank *****

On the 5th of July, I was using the atm in Amalinda and my card was swallowed by the machine. Then I called the customer care and stopped the card. When I went to the bank on monday I realized that money was being withdrawn from my account during the course of the weekend. An amount of plus minus R20 000 was taken. When I enquired about it they said the card was not blocked. They then said they'll block it again so I relaxed. To my surprise more money was deducted from my account. In total an amount of R70 000 was ****** from my account when Nedbank had assured me they had blocked my card on two separate occasions. Can you please assist. I'm a 79 year old man, I don't have the energy anymore for their hide and seek.
