Безопасен ли russianbroadway.com?

Would not trust this website nor buy tickets from them. One of my friends paid a double price for 2 ballet tickets from russianbroadway.com website. When my friend later had to make cancellation because of unexpected travel dates changes, she did not get her money back no matter how many times my friend wrote to them and waited for their response/refund. They promised to refund the tickets but never did. The worst part is that they sell your tickets without sending you valid contact information and they never pick up your phone or return your emails). So I would not trust them at all. Be careful!
