ATM NMFH30cash trapped inside/ personal details

on the 3rd May i did a cash deposit at the ATM around 18H20 or so. ATM showed an error and rejected my card and locked the cash inside R2900 . I immediately called the call center on the 0800 number relayed my story and everything, the gentleman on the other end of the phone advised that he will send me an sms and that i will receive my feedback and money within 48hours. Just to be on the safe side i went to Branch the ( protea Glen) in the morning again i relayed my story and she also confirmed my details advise that the ATM guys will be there Thursday or Friday never the less they will call me and advised that she sent me an sms but nothing. Today i follow up and the call center consulted advised that this takes about 4 to 5 working days so i ask him that 3 people have said 48hours and now it 4 days. He then continued to explain that to his knowledge it takes up to 4 days or 5 days the most. H e now starts to confirm my details and somehow details have been reset to the old details and he confirms a number i have not used in the last 10 to 15 years, i explained to him that i confirmed my details with the bank consultant and the call cent agent on the 3rd and the 4th. I am not certain if nedbank is aware of the risks and dangers as they maybe divulging sensitive issues to someone else as that number maybe sold to someone by now. Can i get my Cash Back and also change my details before i report the Nedbank for breaching confidential issues to 3rd party .
