Narrative:

We were established at 6000 ft heading approximately west and were cleared to descend to 2000 ft and turn to a northwest heading. We read it back exactly as issued. While in the descent, we received a TCASII RA at about 5700 ft. We climbed back up to 6000 ft and reported the RA to hou approach control. The controller stated that we were in error. We completed the flight without incident. I, the captain, called ATC and found that the controller had issued us the wrong clearance after all. The quality assurance representative at the facility said an investigation was in progress.
