Narrative:

We had visual contact with an fgt climbing beneath us. ATC assured us he was level FL250. We began to get a TCASII alert. TCASII said pull up. We pulled up. Fgt aircraft showed 300-400 ft beneath us. At one point ZTL advised fgt he was 500 ft high. Fgt aircraft leveled and then started another climb. At this time I demanded and received an off- vector heading to stay out of the fgt aircraft's position.
