Bonkers fraud checks that flagged my ISP charges every month for several months in a row. And some other stuff I don't remember, but I'll continue to hold the grudge anyway because there's 9 other top 10 national banks. Or at least 8, cause I'm not using Wells Fargo either (they dinged me a phone teller fee when I called in to let them know I was fixing an overdraft) ... Wells Fargo doesn't do a lot of attractive credit card offers though, so that's less of a hardship than ignoring Chase.
