Yeah. I had this happen once when a Canadian car rental agency incorrectly charged me some multi-hundred dollar fee. I called them, they reversed it, but after forex, I was out a couple dollars. A quick call to Chase saying "I didn't authorize the transaction, and they have subsequently refunded it" got them to credit the difference.
