Narrative:

Air carrier X approaching gua VOR level FL330 assigned, sighted the contrail of an aircraft approaching from the opposite direction that appeared to be at our altitude. At about 5 mi separation, I began a left turn to provide separation, as the approaching aircraft was coming from about 11 O'clock. As the turn was initiated, we received a TCASII alert to climb. I climbed the aircraft to FL338 and the other aircraft passed below and slightly to the right of us. It was air carrier Y MD88. At time of passing, TCASII indicated an altitude difference of 400 ft. The incident was immediately reported to eza control, but we received no information from the controller, who was engaged in a continuous conversation with Y pilot. We requested that their conversation be conducted in english so we could know what was going on, but we were ignored, and their conversation continued in spanish. Later that evening, I was contacted at my hotel by captain X, who idented himself as a chief pilot with air carrier Y. He stated that he was investigating the incident and that the involved controller assumed responsibility for the incident. Supplemental information from acn 305882: approaching gua at FL330, saw aircraft coming from opposite direction. TCASII said at our altitude. Got the RA, captain did the climb. Missed by 400 ft. Lateral separation of quarter mile. Notified ATC of complying with RA. ATC did not respond. Called between 5 and 10 times without response. Heard other aircraft conversing with ATC after we passed. I asked them to speak in english. No response. Never did get them to address the near miss. We were on 125.6, ezeiza control, the next time they spoke to us they switched us to baires control, 124.9. TCASII worked great, as advertised. Biggest complaint is spanish spoken when english should be.
