Missing Funds

I was accused of ***** and my account frozen. I was innocent and proved this by going to the SAPS and clearing my name. I sent all documents and statements through and eventually my account was released. During this time funds were paid into my account. These funds are still missing and upon contact with the bank and various supervisors etc, 3 months later still no response or any assistance from FNB as to where my missing funds are. It was not sent back to the sender as I have proof thereof. The normal response I receive is usually that they have no idea what to do or to which department to refer me, resulting in me contacting almost all numbers etc I can find on the internet. Not only is my money missing, to this day I have not received further contact by the bank as to resolving this issue while they know of the situation and I regularly send emails asking for updates relating to my situation.
