Bank robbery statute of limitations is two months

Today I closed my Chase bank account. I was with them for 20 years. I closed my account years ago because they started charging me a fee. One day they invited me back and I explained my past experience. They promised me a free checking account. So I opened the account. A few months ago I noticed I was being charged a fee. So I pointed out that they had offered me a free checking account and then started charging me a fee. I explained that I felt like they had stolen my money and when I pointed out their mistake they offered some of the money back but they felt because I did not report the previous crime early enough. They reversed only two charges. They must've felt the statute of limitations of bank fraud by the bank is two months. I think bank robbers should have the same statute of limitations then criminals will at least feel they are being treated fairly. Anyway I am glad my own actions coincided with millions of others who are closing their bank accounts.
