OnlineTicketOrders.com MyTicketTracker.com Company cannot replace tickets I had lost even with confirmation. Internet

I had purchased 2 tickets to the Michael Jackson Cirque du Soleil show at the United Center back in January.  The show was for July 21st.  I received the hard stub tickets in the mail.  Unfortunately I lost the tickets in the process of moving.  I have my email confirmation for the purchase.  When I called OnlineTicketOrders.com they said they cannot replace the tickets nor give me a voucher.  They asked me to call the venue itself.  The United Center said they could not help because I bought these tickets from a third party.  If I had bought the tickets through them directly they could still get me in.  I left a message for the manager at OnlineTicketOrders.com and am now waiting for a response.  I am not asking for a refund.  I just wanted to surprise my wife for our anniversary with this show.  I have the credit card and identification and confirmation.  I just don't understand why they cannot give me comparable seats.  They wanted me to buy 2 additional tickets.  I make just above minimum wage and they want me to shell out more money?  I spent over $200 the first time.  I called nearly a month before the event and still they cannot help me.  I will NEVER use this company again.  Upon further research, I see several complaints filed against them.
