The R9000 that was ****** in my partners account

Old mutual money account bank stole my partners R9000 and the branch manager saw that the money was transferred from my partners account to another money account holder yet they did not do anything about it they kept on saying they still investigating since May until now and the Gardner Street branch manager when he goes there to ask for a feed back he told him that they can't help him it not in their hands anymore I will never ever trust that bank ever they are cruckes.
