No feedback after ***** on my account!

On 24 December 2022 money was taken out of my account without my knowledge. I immediately called NEDBANK and they advised me to block the account and my online banking. Apparently, my online banking app had been hacked and that is how they got my money. To date, I have received NO FEEDBACK! They said that they would call the following week and still there has been no call. I have since moved the majority of my money to another account and I'm updating my debit orders. Nedbank clearly doesn't give a damn about my money or me. They have not contacted me about their investigation as to HOW someone hacks my app when I had my phone the whole time! They have been silent meaning I must just accept my money is gone because it's small change to them? My advice to any wanting to join Nedbank, DON'T! Their app is not secure, they have terrible service and don't care about people.
