Frozen account

I had money in my notice account, now when I want to have the funds released to me I was told the funds came from a source that was under investigation. Then they went on to freeze my account for nearly two months now. Never have I been given a straight answer always give a date by which my funds will be released. Now they unfrozen my account but still yet my funds are still unfrozen and noone gives me a clear indication on what's happening. Standard bank must just release my money, that's all I want so I can be done with them
