Narrative:
Original clearance was: after miq, UA315 diman UW27 roner UL304 brs UW1 cpn dct stn dct sbgr. Approaching kamut, ATC issued new clearance: after kamut, UA315. This was an incomplete clearance that did not terminate at our destination. We were denied a request to maintain the original clearance. We initiated a course change to comply with the new clearance while asking for clarification of the down-line clearance. This request seemed to annoy the controller but after repeated requests, she issued a clearance to maintain UA315 to man, then UW9. Again this clearance was incomplete as no end point was specified. It took nearly 20 mins of repeated requests and long pauses to finally obtain a complete clearance to destination at XX14Z. Throughout this period the controller never seemed to understand that she was issuing incomplete clrncs, only clrncs that would take us out of columbian airspace.

Title: B767 FLC HAD COM DIFFICULTY WITH FOREIGN CTLR OBTAINING A COMPLETE ROUTING CLRNC. CTLR REPEATEDLY ISSUED INCOMPLETE CLRNCS.
Narrative: ORIGINAL CLRNC WAS: AFTER MIQ, UA315 DIMAN UW27 RONER UL304 BRS UW1 CPN DCT STN DCT SBGR. APCHING KAMUT, ATC ISSUED NEW CLRNC: AFTER KAMUT, UA315. THIS WAS AN INCOMPLETE CLRNC THAT DID NOT TERMINATE AT OUR DEST. WE WERE DENIED A REQUEST TO MAINTAIN THE ORIGINAL CLRNC. WE INITIATED A COURSE CHANGE TO COMPLY WITH THE NEW CLRNC WHILE ASKING FOR CLARIFICATION OF THE DOWN-LINE CLRNC. THIS REQUEST SEEMED TO ANNOY THE CTLR BUT AFTER REPEATED REQUESTS, SHE ISSUED A CLRNC TO MAINTAIN UA315 TO MAN, THEN UW9. AGAIN THIS CLRNC WAS INCOMPLETE AS NO END POINT WAS SPECIFIED. IT TOOK NEARLY 20 MINS OF REPEATED REQUESTS AND LONG PAUSES TO FINALLY OBTAIN A COMPLETE CLRNC TO DEST AT XX14Z. THROUGHOUT THIS PERIOD THE CTLR NEVER SEEMED TO UNDERSTAND THAT SHE WAS ISSUING INCOMPLETE CLRNCS, ONLY CLRNCS THAT WOULD TAKE US OUT OF COLUMBIAN AIRSPACE.
