On 2/28/2019, I took off from San Antonio, TX to Mexico City one stop then into Bogota, Columbia I had no problem. When I returned from Columbia on 3/7/2019 into Mexico City, they held me there and did not let me board my flight to go to San Antonio due to my ticket name Melinda not matching my legal name on my passport I don't understand there was no problem coming in with my name then all of a sudden going back home they held me....I talked to 4 different departments of AeroMexico Airlines to change my name in order to board my flight and they refused to and made it really hard to understand due to language barrier, they made me buy another airline ticket in order for them to put my legal name on the ticket....it cost me 768.13 and I am now needing to get it refunded. I have send an email to the airlines and have not received a response. Please let me know what I can do to get this refund asap, I am a single mother of 3 and this has put me in a financial bind....any information on how to go about this is greatly appreciated. Thank You!
