I tried but couldn't cancel the trip. I'm flying alone as I'm the person responsible for the export department. I have decided to search for other companies and meet them when I'm there.
The friend who linked me said she knows him for like 10 years. However, everything about him looks very shady. I called one of the called contacts, and the guy said that he can't give any details about his business over the phone...
I think scams are everywhere, and when we're in business there is a big chance to get exposed to crooks like this guy.
