Atm *****ing money

I made a deposit at ATM got slip saying technical error and money was retained. I logged a complaint at the branch received 2 reference numbers and an sms saying outcome me declined. I queried this branch advised atm balanced need to contact or email call center which i did with no luck or feedback on my email. Is Nedbank atms *****ing money now? I sit with my proof my money was retained and no one interested in helping ng me getting my money back. Would like a maanger to call me back asap pathetic service wouldn't recommend Nedbank to anyone
