NEDBANK STOLE MY MONEY

I deposited R6700 at Nedbank ATM woodmead but the ATM went off while I was busy, the money is gone, I spoke with more than 10 consultants who said unfortunately they cannot help me, I tried to talk to the guys inside the branch but the Indian guy said he cannot help, I stood next to the ATM for about 40 minutes just incase the money comes back but nothing, nedbank ATM guys stole my money
