I was making a XXXX Airline reservation, when I was offered a credit card that showed the cost of the ticket would be {$100.00} less, if I applied and was accepted. I applied for the card, was accepted and notified that I could use it to make purchases right away. Went back to the reservation web site and indeed the cost of the ticket was {$100.00} less. BUT, timed out during the process. Now I am not able to receive the {$100.00} discount on the ticket. I have been told several different stories regarding this issue. I was told to use the card I will receive the credit. I tried this and card would not work. I was told by Citi that getting timed out happens and the credit card company can work with AA to get it fixed to make purchase. Finally, I was told I can not use the card for 7 days until it is activated and they can not cancel it until it is activated. Bottom line, this was false advertising, the reason for my getting the card I am not able to take advantage of. I have spent many hours over 3 days with no resolution.
