De*****ed by Nedbank

I am Ms Masekela banking with Nedbank . On the 22/05/2025 around 13:00 received a call from Official at nedbank. the Official indicated that she is from nedbank by the name of Pretty Mo***eng Personnel no ND408031. the Official wanted me to open my app using my id no and she indicated all the instructions inside the bank, which really shows that it was inside job. The Official ****med me R8400.00. I phone the bank and being told to open a case no and do affidavit which I did. the reference no for my case was Ref***6. In June I was given the name of the person that is dealing with my case at the bank by the name of Thelma Kesi. the Officials did not handle my case professionally . I ended up with escalating the matter to her boss which still the same. I was told in the bank that the R4400 was send to Capitec and the other R4000 was done cash send. I am saying if the bank find out the other money they knew who the person is which is the bank 's responsibility to deal with the matter. I was refunded the R4400 after that I was told by Thelma that the other money which was cash send the bank will not refund me. I send her an email that what ever she communicated through phone must be in writing but there was no respond. the question that I am asking myself is that Nedbank does not have insurance . it really indicate that our money are not save with nedbank. I really need help with this matter as the bank is not refunding me the R4000 that was internally taken from my account.
