Our flight from Sacramento to Chicago on June 03, 2007 was canceled due to the mechanical problems. We live abroad and bought the ticket via a travel agency in cash. Customer service told the ticket will be refunded soon last year and we are still waiting for a positive response. I called and emailed them several times, however no refund yet. It has been more than 7 months now. How may I get a refund of 630 USD. Plz advise smb!
