Over the past couple years, hundreds of you have asked Whistleblower for help. While we can't investigate each tip, we want to share more of what you tell us. In 2009, we started publishing a few tips each week to stimulate online discussion and create ways for our readers to help each other. Unlike our news stories, we have not verified this information, so we do not include the names of the parties involved. If you have a tip, send it to whistleblower@startribune.com. Overdraft fees have long been a source of frustration for Whistleblower readers, but one bank customer shared his story of an irritating variation. He has a weekly automatic transfer set up that moves $400 from his checking account to his savings account in the same bank. One week his checking account was slightly below $400, but the transfer went through anyway. He was hit with $175 in overdraft fees.

"I can understand being charged an overdraft fee for buying something without enough money in my account," he said. "But to get charged an overdraft fee just by moving my own money around is ridiculous."

New laws have made it harder for banks to charge overdraft fees, but are they still popping up for unexpected reasons?
