The overdraft thing was actually a shift in topic; in the event of a non-fraudulent charge that is reversed by the merchant things like that can happen (with me, it was an airplane ticket where the airline rep messed up, did a refund and charged the correct flight all on one phone call), when the two charges go through before the refund (even if they all post in the same business day), there is an overdraft charge and Chase refused to refund it.

The point was that my experience with Chase sans fraudulent charges makes me believe that it would take months to see the money in the days before it was illegal for them to do so.

Since you mentioned Citibank, I've never banked with them, but I did have a visa with them back in college. I was young so only had the card for 18 months, but I'd never had a single late payment when a bill got put in the wrong mailbox in my dorm. By the time I got it, it was 2 days before it was due. I called up Citi (2 days before the due date) and asked them if they could waive the late fee/interest provided it was posted the following day. The answer was no and they had an additional fee (which they also wouldn't waive) for doing a bank transfer, which would save me from the late fee. I told the I'd do that and to please close the account. Asking to close the account got me to talk to his manager, but they didn't bend on any of the fees.

I've had much better customer experience with credit cards from Discover, American Express and (somewhat ironically given my banking story) Chase.
