My EVA AIR flight to the Asia bought from Just Fly was placed on "Waiting list" 4/29/2021 because Just Fly failed to reissue my ticket to the airline on time, as stated by EVA air agent during my call to them at 8pm. I was directed by the agent to contact Just Fly. I tried to contact Just Fly soon after my call to EVA AIR when I was placed on multiple HOLD some for over 15 min. Because of these long holds, I accepted the option for a Call BACK. The Call back was returned after 8am the following day, 4/30. Not getting the resolution on time, I had to cancel the flight. For this, I am being charged by Jet Fly for processing fee of $75!!! and had to pay a $200 cancellation fee: Extremely unfair as the root of the problem is JUST FLY's delay and inability to resolve issues on time.
