I've got a problem on Sunday 18 December, I was in the ATM to withdraw the money with the Overdraft card. I put the card in the machine I do everything in the machine like pin but when I wrote the amount I like to withdraw the machine said the transaction declined, I tried to cancel but the card doesn't coming out. I go back home because my phone was in my house and I found the messages reported the money out and swiped the purchases. I tried to stop the Card it was late. My problem is that African Bank said they can't help me to replace my money and I've got the footage for this guy who take my money to my card and I opened the case to the police station. Now what must I do
