have your people call their people

Or.... if you don't have any people (yet!), call them yourself.
Today I found a grand total of $164.38 in unauthorized charges and fees that by bank helped me recoup.

Lets hear it for Wells Fargo!

Wow. That was officially the first time such a statement has ever escaped my lips. Who knew you could be BFFs with your bank?

Access your old statements, print them out and give them a good combing through. You'd be surprised what those guys are willing to do to help lower or eliminate annual fees, credit card percentage rates, etc.

This also works with phone companies as well as cable and internet providers.
