Years ago, Wells Fargo taught me not to trust banks.
They told me with straight faces:
1. It is my fault for not noticing the FREQUENT CHANGES in the fine prints
2. Their system don't have any tracking info, so they can't tell who made the mistakes/changes
3. They'd only refund up to three months' worth of wrongly charged fees
I was convinced that they purposefully make "mistakes" to overcharge me. And they SHAMED ME for not checking the statements more closely.
