TACA Airlines review: Worst Customer Service Ever

We went to the airport to take a flight for argentina after having a problem with the rented car, so we were kind of late, but the flight was not closed yet, they didn't take us in. We went back to the airport the next day as we were told on the phone by TACA Customer service, the lady at the counter (Lili Pinto) was the nastiest person I ever met. Nobody ever made me feel as bad as her. I was really mistreated. I requested to talk to the supervisor, who was not available, after a long wait he showed up, washed hands and leave. When we requested for him again we were told he was going to take more htan half an hour to come back.
This woman, Lili was trying to sell us a ticket for $3, 000.00 and told us if we were not going to buy those tickets she didn't have time for us.
She was laughing about us with the other people at the counter, they were making fun of us, thsy just didn't care about our needings nor our problems. I tought they are there to help people and give a service. Well, there was not service at all, just a bunch of disgusting people getting paid to do the minimun effort.
Please don't flight TACA, if you have a problem they won't fix it for you!
