About two years ago, my credit union started taking lessons from national banks. Charged late fees on a two loan accounts that had never been late (auto-drafted payments from a direct deposit destination); charged me for a replacement debit card when I reported one stolen; can't figure out that "wiring money" is actually free and points me at a third-party service they've hired for transferring money between banks - there's a fee for that; converted my free checking account into a fee checking account without notice.
In all these cases, I could not get the fees reversed on the phone, but had to visit a branch in person, where the branch manager was indignant that I had the gall to rob the financial institution of their fees. I did get the fees refunded. And two weeks ago, I closed all my accounts with them.
I am fortunate to have a community bank that acts the way my credit union once did. The only quibble I've ever had with them is with the staff not knowing the rules on overdraft fees.
