Open Question: Fifth Third Bank discontinued inactivity fee on their Credit Cards?

I received a notice last year that Fifth Third had implemented a $19 inactivity fee on their credit cards. I had a balance on the card that was paid off in the last couple months. So I called to cancel the account (I'm not willing to have a card that may charge me even if I don't use the card) and they told me that they discontinued the fee as of March. But, they aren't (and won't be) sending out any written notification of this change, and everything on their site still shows an inactivity fee. Has any one else been told this from Fifth Third? I'd like to keep the account open, for the credit score implications, but I'm a bit worried that they're not putting anything in writing.
