My bank account emptied because of FNB *****ulent transactions

My bank account was emptied of a lot of money through *****ulent transactions, I did not receive an OTP to authorise the transactions. I lodged the complaint on 07 November via the ***** department and when I followed on 09 November, was told that the investigation has been completed and that my complaint has been rejected. Reasons given were that, FNB ran a full investigation and the bank or its employees were not involved. I was told FNB has declined my request for refund because I am the one that I approved and authorised such transactions through my device. How does a full investigation take one day to be completed, even? I found this to be appalling because no request for me to approve the transaction (as per norm) was sent to my device. As a client, my money was not protected and FNB is not taking any responsibility for this. The call centre person kept blaming me and insisting that I “pressed some link”. I need a refund of every cent that was *****ulently emptied from my bank account. This is causing a huge inconvenience for me.
