Faulty ATM did not receive my money

I am so disappointed with Nedbank after I couldn't access my cash send money at the ATM in their branch in Oxford East London because the ATM went blank and couldn't work and after their reboot the machine it worked but i couldn't get the money.I reported it immediately made a call to client services after having called them nothing has been done to solve the problem even the following day they still say my issue has been registered but not yet attended to. I mean this ATM is in the branch. Poor service to be told that they will look into and will come to Me within 7 days. I don't understand at all they could have reconciled the money in the ATM same because this is happening within their branch. MY LIFE STUCK CANT TAKE MY SON TO HIS DOCTOR SO UNFAIR
