Pretend to be "Thai Airways", utilising the same colors and layout of the official Thai Airways website.
The trick you into thinking you are on the Thai Airways website. They then charge you double the price, and send you a fake 7-digit booking code. They then buy your ticket from Thai Airways, reissue a correct 6-digit booking code and seek to pocket the difference.
THEY ARE A TOTAL SCAM
It is not thai airways, it looks like thai airways but it is not! You book the ticket and then they charge you the double. I asked for reimbursement, I think I lost my money, I suspect it is a scam!
