Mariah Carey

I want to go to the Mariah Carey concert SSOOO bad!! She's going to be at the Staples Center on October 3rd. I think that the only way to go is to win the tickets or buy them and i really want to win them but i never get my call through. I called once but they said that they wouldnt give tickets until 7:00. So then i called and i called but as usual i never got through. I would really want my christmas gift to be a Mariah Carey Concert Ticket.
