Hi FlyerTalk folks,
I have been trying to get a flight to go back to my home country for the past three weeks. At first, I tried to book a ticket for EVA AIR from a website "cheapoair.com", my flight got canceled and they booked me another ticket for the next day. Turns out that they would not let me fly on the next day due to overbooking. They did not compensate me for anything and asked me to try to book the ticket straight and directly from their official website, so I did. I bought another ticket from Eva Air website and the same "overbooking" issues happened again. Then I decided to switch to another airline, Air Nippon Airways (ANA). The same thing happened all over again with ANA, they would not let me fly because my ticket is not valid and they could not pull up my information or booking number from their system.
In addition, I tried to switch airport from SFO to OAK. I booked a ticket from China Airlines flying from OAK intl airport.Booked the ticket straight from their official website. yet the same issues happened all over again. They said that they could not find my booking info in their system
I'm not sure if this has to do with an error in their system or something else. I even tried to contact every phone number that I can possibly find in the airport site, yet they could not help me resolve the issues, and claimed that they have never encountered this issues before.

Just wondering if anyone has experience similar issues before? would appreciate any pieces of advice and suggestions

thanks
