Disappointed after-sales service, this agency only cares about selling the ticket. I had my flight time rescheduled by the airline and I was informed by the agency about six months before, but there was an impediment to keep the trip with the new time and when I tried to contact the agency, it took more than 24 hours to get a return and not effective because they answered out of date and claimed that I couldn't get a refund when cancel the flight. I never asked for cancellation, I asked for reschedule and possible dates but the service did not finish. It's more difficult to negotiate by message, although they say that there is an on line way to speak with them, it doesn't work, I have spoken to three different employees and all of them did not finalize the conversation.
