Talk to the branch manager. If that fails, threaten to talk to the Consumer Financial Protection Bureau[1] (which is a branch of the federal government). That will almost always cause the bank to become much more helpful. If they don't, well, actually talk to the CFPB. They have a fair amount of clout.
