Hi! Can you help me regarding this cancelled flight from EVA air? I booked a flight same as my cousins flight in order for my mother Criselda Folloso to be accompanied by my cousin. But the flight was cancelled by Eva air. I’m trying to reach Vayama as I received the cancelled flight in my email. But I’ve been waiting for how many days and they still not update me regarding this. They say I need to wait **-**hours but I’ve been waiting a couple of **hours. I need my mother to be here in July *th in Chicago because we already paid a van to pick them up in the airport. I was just wondering that my cousins flight was change right away by the ASAP tickets, they offered a new flight for exchange to another airline. But Vayama is so slow even in replying me back. I’m hoping that they can change my mothers flight same as my cousins flight because I need someone to accompany my mother when she feels dizzy ‘cause she has a vertigo. Please reply me back.
