They claimed they are the flight company representative on phone but they are actually not. I found out their phone number by google “EVA Air flight ticket cancellation ” and called them to seek help from EVA air. The representative said she is EVA Air but actually she is from the third party. Then she asked all my information (credit card, address, etc.) to pay the transaction fee but what she did is to use my credit card for $200 for the service from airlinesticketpolicy. I tried to question and told her to hold on but she said I must finish the transaction on the phone call. I gave out the information under the pressure from the representative. It’s a scam because they claimed they are from the flight company but they are just a third party. 1. FYI, they will charge you additional money for their service ($200 in my case), which you can do it on your own completely 2. If you were asked for your personal information, just hang up the phone and just reach out the flight company. 3. They will advertise in some websites (medium[removed by editor] in my case) to mislead you to think the phone number is from the flight company.
