card cloned and money ******

My sister used atm on my behalf as I was in an accident and was unwell. The atm was out of funds she pressed cancell.it requested cell number when she cancelled it asked for id number she n pressed cancel and card was retained she waited few minutes and the atm was then back in home screen. By the time I can cancel the card 1500 was withdrawn from my account. I went to the bank jus for the lady to tell me im wasting my time sendin a claim cause I wasnt at the atm. So i told her my situation then she says send it and see what happens. I mean im a platnuim card holder. They should be looking for a way for me to have my money refunded to me not be unhelpful.i will ensure that I get my money refunded to me.will really like for a person from fnb who can assisst me to call me back<br> Thanks s.reddy
