I booked my flights on Kayak and did not realize that Vayama was the agent handling the tickets. I thought that Kayak was a reputable company. My sister is in the middle of a divorce and I used her married name when making the reservation but then came to find out that her new passport is in her maiden name. I called Aeromexico to get it corrected and they said no problem but it will cost $150 to which I had no objection. Their agent tried to complete the transaction and was unable as the ticket was "in the possession" as he put it of Vayama, I would have to contact them. Vayama is telling me that Aeromexico will not allow the name change which is a lie, I have called back to Aeromexico twice to inquire with the same results $150 is the fee. Vayama says I have to cancel the ticket which is non-refundable and purchase a new one. The flight is now sold out so that is not an option. Does anyone have any suggestions, I am totally at a loss at this point.
