Narrative:

Previous controller had cleared us direct to MLS 182 degree radial/45 NM then sent us over to center frequency 127.75 and we checked in at FL330 going direct to above fix. About 2-3 mins later control called to confirm we were on 030 degree heading. We said no that we had been cleared direct MLS 182 degree radial/45 NM. He said to then turn left to 030 degrees immediately which we did. A few mins later we were again cleared to direct MLS 182 degree radial/45 NM. No other comments were made. We feel that the previous controller either had not informed the new controller or the new controller missed or forgot clearance.

Narrative: PREVIOUS CTLR HAD CLRED US DIRECT TO MLS 182 DEG RADIAL/45 NM THEN SENT US OVER TO CTR FREQ 127.75 AND WE CHKED IN AT FL330 GOING DIRECT TO ABOVE FIX. ABOUT 2-3 MINS LATER CTL CALLED TO CONFIRM WE WERE ON 030 DEG HDG. WE SAID NO THAT WE HAD BEEN CLRED DIRECT MLS 182 DEG RADIAL/45 NM. HE SAID TO THEN TURN L TO 030 DEGS IMMEDIATELY WHICH WE DID. A FEW MINS LATER WE WERE AGAIN CLRED TO DIRECT MLS 182 DEG RADIAL/45 NM. NO OTHER COMMENTS WERE MADE. WE FEEL THAT THE PREVIOUS CTLR EITHER HAD NOT INFORMED THE NEW CTLR OR THE NEW CTLR MISSED OR FORGOT CLRNC.
