There's a hallmark/lifetime movie about this. The bank isn't WF but we all know who it is.
After his corporate rah-rah and disbelief his bank full of good ethical people would do such a thing, at the behest of the main character he finds out from some marketing chuds it is in fact true. Believing in the company to do the right thing he goes against the main character's wishes and tells an exec who expectedly closes the accts of the vocal customers and sweeps it all under the rug - deleting all record.
The love interest finds out his company doesn't actually care about their customers when he asks if they are going to do a full company investigation and the exec laughs and instead offers up a potential promotion instead.
I knew the whole plotline was bullshit when he quit to become a whistleblower. As he gave his first interview on the main character's tv station, he gave his full name as he did a live interview and didn't get murdered by the bank immediately.
Thanks to Boeing we all learned that whistleblower is a far more dangerous profession than police officer and the chance of dying is thousands of percent higher. You really have to suspend disbelief at the movie plot.
