I just did this a few months ago after Wells Fargo pulled an insane stunt on me. The day my family went on vacation they froze my account for two weeks. I spent my entire vacation begging, pleading, and fighting Wells Fargo. Zero help and zero sympathy from them. I closed all my accounts and my credit card with them (they couldn't have cared less) and went to Key Bank. Not a credit union, but I feel your Wells Fargo pain. There is something deeply wrong with that company.
