American Airlines Screwed by website glitch Internet

I tried to purchase tickets online for two flights to Chicago today. At the end of filling in all the information, I received an error message that said something like, "Sorry, unable to process at this time. Try again later." So, I did try again 5 to 10 minutes later and got the same error message. I decided to wait a few hours before trying again but later when I checked my email I had received four tickets with two different confirmation numbers for the same people. Apparently, the transaction had gone through twice anyway. Thank God I didn't try a third time. When I called customer service they said they'd be able to reimburse me in 1 to 2 months! So, I'm holding payment on my credit card, racking up interest for two months on plane tickets I didn't want? When I pointed this out, they said it was my fault, that I made the mistake or just decided I didn't want the second set. Of course, I replied with the question, "Why would anyone want two sets of tickets for the same itinerary? It would be impossible to use them." So, I'm out cash for their mistake and they couldn't even offer me some kind of discount on my next flight or an upgrade or anything for my troubles... Bad business.
