Unfair and horrible service

In 2018 money was transfered into my account my account was blocked. Upon enquiry I was told the money was ****** from another bank and transfered into 2 accounts and redistributed into a further many accounts. 10 bank accounts of capitec were affected. I was told there would be an investigation. Upto date nothing has been done. I have been to the police station and capitec bank numerous times. My account has since been frozen and I can't access my money which I had saved. No investigation has been done thus far.
