We are from Brazil and We've bought tickets for Metallica's show in S. Paulo next May, 10.
Til now we didn't receive the tickets and, unfortunately, the StubHub Brazilian website is not working...
No one answers us by mail, the only channel of contact available.
What can I do?
this is a good place to start and hopefully a moderator here can help you. I was in a similar situation and I wish I had tried to sort it out sooner than the day of the event. Keep calling on the phone if you can and wait for a message here. Good luck. It seems failure to deliver tickets is a common thing after browsing these forums so you aren't alone
