StubHub.com Stub Hub Stole My Ticket and wont Compensate me San francisco, CA Internet

I decided to sell my ticket to a concert I was not attending on Stubhub.Two days after I placed the ticket for sale, the company claimed there was a glitch in their system that kicked my entire entry out as fraudulent. Then there is something wrong with their system because my tickets were legitimately purchased on an American Express card and were part of an 8 ticket package. My sisters and their husbands attended the concert. I am the only one who did not and placed my ticket for sale on their site. THEIR system mistakenly threw out my entire entry but when I called to ask what happened and get my money back for what happened they decided to penalize me by not compensating me for a loss that was their fault. They claimed they cannot assist me and now I am without the price of the ticket and no financial recourse from them for a mistake their system made. Their fraud/legal and customer service department were of no assistance and wasted my time on the phone with them. Now I am without a ticket and without the money for the sale of the ticket. I could have placed this ticket on Ebay or Craigslist or any number of sites and sold my ticket.The fact that they have just disregarded any opportunity to assist me as this was my first transaction with this company is very disappointing. I will never deal with them again. This company is a fraud.
