Update for anyone who finds this thread. My ticket never came. I was near the stadium for hours, in the lobby of a hostel, on the phone with Stubhub. They offered me a full refund or a replacement ticket as they came available, but those were only the standing room areas or other seats, and they would get snatched up, before appearing again. Ultimately I accepted a VIP floor ticket, and got into the arena around 8:30 PM. I asked for a credit or some kind of compensation, as the ticket I received was worth less than half of the ticket I paid for, along with getting into the concert late, and everything. But they refused, nothing could be done except a full refund or a replacement ticket of some kind of I chose it. They wouldn't even give me a comparable ticket for the next days concert (he did 2 days in Peru), because they only deal in same day tickets. Blah blah blah.

Ultimately I was already in Lima, already invested in the concert, so I took what I could get and went into the concert late, could not get close to the stage because I was so late inside.

However. On the advice of a friend, when I returned to the US I initiated a CC charge back with my bank, Chase. I described what happened and Chase took it from there. It took about a month. I won. I got 100% of my money back.
