Hi does anyone know how I can email Justin Bieber?

My name is Tiffany, I purchased 2 tickets for Justins buổi hòa nhạc Aug 31st at madison square garden in NYC. I purchased the 2 tickets so I could take my 8 năm old daughter cause she adores Justin Bieber, it was supposed to be a birthday present. To make a long sad story short. Ticketmaster was sold out so I went thru a ticket broker and a person who claimed he was the nephew of the owner of the company, it turns out the guy who sold me the 2 tickets is a scam artist, who is illegally selling FAKE tickets..... my poor daughter is tim, trái tim broken, and I am out quite a bit of money. I figured I would try to get the message to Justin to see if there was anything he could do to help! It upsets me to see her so sad... Help!!
