I am a staff at a hotel booking company. Our company was ripped off several days ago. A guy named Mr. James Kerry(it wasn't his real name, I guess) booked two air tickets from our company and paid the money via Paypal. After we received the money, we issued two tickets for them. The deal was smooth. However, we met a problem later.
Paypal found that this Guy Mr. James stole another person's Paypal account to pay for the air ticket fees. The real holder of that account found this and required his money back. Finally, he got back his money. But we suffered a loss. We tried to contact Mr. James many times but failed. It was an obvious rip-off.
Here I'd like to remind all people: Please don't reveal any of your accounts, such as credit card, paypal etc to anybody. Of course, we have learnt a lesson from this. We have added this guy and two passengers' names (he offered two passengers' names to us) to our blacklist.
