Narrative:
While climbing to FL270 I was told as I was going through FL250 that my assigned altitude was FL250. We hurried back down to FL250 and min later an aircraft passed over at FL270. I believe that we were assigned FL270 originally and that the controller was in error. There was no close call, but may have been if we did not catch it when we did. I have the PNF always read back an altitude that was assigned, and I will emphasize this from now on.
