Too hard to get a refund, last month i email, today i call them, next week i will fly to US to see them maybe.

Does anyone know how to sue a company from oversea?
Isn't Black Arrow in China though?

The question of where Black Arrow are located has been vociferously debated for at least the last three months on this thread.
It's easy really, if they were legit they'd publish where they are located but they don't, do they?
