Narrative:

I was flying inbound to ftz VOR on trake 7 arrival into stl. Stl was using runways 12L&right. Controller told us to turn left to heading 020 degrees at snydr intersection (21 DME on ftz 082 degree radial). First officer and I thought that odd since that was rather close in to turn us for vectors for ILS runway 12R at stl, but we did not query him. We went past coors intersection at 10 DME on ftz 082 degree radial and somewhere between 15-20 DME on ftz 082 degree radial the controller caustically remarked 'you missed your turn.' I told the controller he said turn to heading 020 degrees at snydr intersection. (I might add as typical with stl controller he did not acknowledge my first officer's transmission or correct my first officer's supposed error when my first officer first read back the controller's original instructions.) he then said turn left to heading 350 degrees and left it at that. Factors affecting incident: 1) controller not listening to our readback to catch his original error. 2) first officer and myself not querying controller about 'odd' instructions. How to prevent incident: 1) controllers must listen to pilot readbacks. 2) pilots should question controller about instructions that may be in error.

Title: FLC OF A JETSTREAM 32 FAILED TO TURN AT THE INTXN INTENDED BY ATC CLRNC ON A STAR ARR DUE TO THE FAILURE OF ATC TO CORRECT THE FLC'S READBACK, AND THE FLC'S FAILURE TO QUESTION THE CLRNC GIVEN BY ATC.

Narrative: I WAS FLYING INBOUND TO FTZ VOR ON TRAKE 7 ARR INTO STL. STL WAS USING RWYS 12L&R. CTLR TOLD US TO TURN L TO HDG 020 DEGS AT SNYDR INTXN (21 DME ON FTZ 082 DEG RADIAL). FO AND I THOUGHT THAT ODD SINCE THAT WAS RATHER CLOSE IN TO TURN US FOR VECTORS FOR ILS RWY 12R AT STL, BUT WE DID NOT QUERY HIM. WE WENT PAST COORS INTXN AT 10 DME ON FTZ 082 DEG RADIAL AND SOMEWHERE BTWN 15-20 DME ON FTZ 082 DEG RADIAL THE CTLR CAUSTICALLY REMARKED 'YOU MISSED YOUR TURN.' I TOLD THE CTLR HE SAID TURN TO HDG 020 DEGS AT SNYDR INTXN. (I MIGHT ADD AS TYPICAL WITH STL CTLR HE DID NOT ACKNOWLEDGE MY FO'S XMISSION OR CORRECT MY FO'S SUPPOSED ERROR WHEN MY FO FIRST READ BACK THE CTLR'S ORIGINAL INSTRUCTIONS.) HE THEN SAID TURN L TO HDG 350 DEGS AND LEFT IT AT THAT. FACTORS AFFECTING INCIDENT: 1) CTLR NOT LISTENING TO OUR READBACK TO CATCH HIS ORIGINAL ERROR. 2) FO AND MYSELF NOT QUERYING CTLR ABOUT 'ODD' INSTRUCTIONS. HOW TO PREVENT INCIDENT: 1) CTLRS MUST LISTEN TO PLT READBACKS. 2) PLTS SHOULD QUESTION CTLR ABOUT INSTRUCTIONS THAT MAY BE IN ERROR.
