Narrative:

Aircraft #1 was a departure off of ord with a climb rate of 800 FPM. Aircraft #2 was in cruise nwbound. Coordination was done to stop aircraft #1 at FL290. I thought aircraft #1 was not on my frequency. The aircraft was on my frequency and was not stopped at FL290. The aircraft was observed climbing through FL290. I made a blanket transmission to the aircraft to stop at FL290. The aircraft went back down to FL290.
