Narrative:

En route cun to mia was cleared to climb to FL290. Passing FL280 requested FL370. Was cleared to FL370 by havana center along with a clearance to offset 12 NM to the north. This was accomplished utilizing the omega. Passing FL310 received a TA followed by a RA. Performed RA maneuver. During maneuver saw oncoming aircraft turning to the north. Passed within 1 mi. When I asked havana what happened the controller stated the other aircraft was air carrier Y and that there was no problem. I disagree with his assessment.
