Nedbank Poor Service

My dad's bank account got hacked on the 31st May 2024 whereby a huge amount of money was transferred into another account.Nedbank called him to say that he's account has been hacked, he followed all the right procedures as he was instructed. He has been sent from pillar to post, emails were being sent from him to the head office as the Nedbank branch advised that they cannot assist him from inside the bank, he should only communicate via email. The person that helped him at first via email is now no longer responding and we are still waiting on a response,it's been 6 months and nobody has gotten back to us we are still waiting on a response.I find this very disturbing as you would think that your money is insured by your bank,but yet your bank cannot give you any proper answers as to where your money went. I am very disappointed and dissatisfied with the service because we still have no answer's and haven't heard from them ever since.
