Account put on hold but no feedback or reasons given

I have a MyWorld Account with African bank. I have been using this account to receive my salary for over 5 years now. i not only receive my salary from this account but my partner (the father of my kids) also sends money through this account. Recently, my account was put on hold and have no idea what triggered this. I have made several phone calls to the bank and all i have been told is that the issue has been escalated to forensics. I have been probing for information and feedback but it feels like i am hitting a brick wall. I do understand and respect that your institution has policies it is governed by, but is the no way that i can get detailed information on basis of my account being put on hold and what I need to do to clear this mess?
