I'm trying to rebook a flight to frankfurt/ germany. I'm in the que for more than an hour. When I finally got through the first time an agent told me the rebooking fee is 300$ plus the difference for the new ticket. Apparently he couldn't find another flight, even thou I told him that I found one. The second agent, after I was in the que for more than 1 hour and thirty minutes again, he told me the fee would be 45$ plus the difference for the new ticket. He found the same ticket I had, everything was the same and he told me I had to pay 45$ fees and an additional 800$ for the difference of the new ticket. I told him that the difference is only 100$ but he said something about new ticket and tickets given back by other customers. When he finally said he's sending an email with an link to pay, I never received an e-mail, neither my daughter did, even thou he sent her the same email
