Narrative:
During descent from FL330 to FL290, ZME called us at FL310 and told us to turn to 270 degree heading and increase descent rate. Then they said we had traffic at 10 O'clock position and 8 mi at FL310 and why we did not change frequencys 5 mins earlier. We complied with heading and altitude and told him we never were given a frequency change. Changed frequency and landed without further to do.
