I booked a return flight with Justfly to go to Laguarda Airport in NYC from MCI . They did not tell me that there was a fee for booking through them and when I got my bill from the credit card company there was a fee of $**.** added to my flight price. This when I called Justfly about it the customer person told me it could not be taken off because it was charged at the same time as the flight charge. This is not fair because they did not tell me at the time of booking that I would be charged that extra amount. Now when I called and asked to speak to a manager the clerk put me on hold and never got back to me and kept me holding on then cut the call off. This is not right. I called again and was put on hold again then told by the machine that i would have to wait * minutes and then it went up to * minutes.
