I need my money. Poor service received.

I am irritated and frustrated with the service I am receiving from this bank.I have an investment which matuared 2 weeks ago. While trying to access the account so I can withdraw,I am told my thumb prints can not be verified The consultant advised me to go to home affairs to which I did and came back with a verified thumb prints letter. The consultant then send it head office so they can release my account.Till today nothing has happened. I came to the bank from the 14th of March till today nothing has happened.I have been coming to the branch almost everyday and still no change,when I call head office no one seems to be able to assist me. I just want my money and close the account. I am feedup with this useless service and treatment I am getting.
