I regret I hadn' read the reviews first. It would have prevented me from everything. They sold me used tickets! What I mean is when I went to the concert and gave the tickets to a person who was checking them, he said that my tickets were already used by someone who came a little earlier than me. I thought that tickets were supposed to be unique. So I missed the concert and it sucks!!! Now I see that I wasn't the only one with the same issue.
