Can't purchase tickets

Cannot purchase tickets for price on website. I have been trying to buy a one way ticket on Jetblue for $80.60 - the ticket has been on the orbitz website for the past 24 hours. I tried to purchase it last night and I when I entered my credit card info and clicked "purchase" I was returned to the search page - last night I got an error message - today it just dumps me back at the search page and doesn't tell me if my credit card has been charged or anything.
I thought this was a glitch last night so I tried again this am. Still won't work - so I called customer service - after talking to 5 different agents - one tried to purchase the ticket so I had to retell her all the info I had already entered and same problem. The agent said maybe the flight is sold out - it is not sold out because there are still tickets available on Jetblue for $144.
The customer service agents offered no solutions - they didn't even over to sell me the ticket at the higher price.
