Negligence leads to the loss of my R24 000

My account was hacked sometime in February where R24 000 was taken and I have still not received my money back. Standard bank advised that I open a case which a number of police stations have refused to as I do not have the suspects details. I have told standard bank this and they still insist, how can I give you a case number when the police station refused to open the case. I noticed the ***** when I received 8 OTP’s and questioned standard bank if this is not suspicious as it has never happened to me ever! No answer.
