Narrative:

Air carrier X on final to dca. We were cleared to land on runway 36. (Clearance issued on approximately 8 mi final). At about 200 ft, we were instructed to go around because there was another aircraft in takeoff position on runway 36. I telephoned the tower later and was told that I had been cleared to circle to runway 33. I never received or acknowledged that clearance. Landing made without incident on second approach.
