JustFly.com is a horrible airline booking site

This website came up through Kayak. The flights that I wanted and thought that I was booking were not the ones that came up on my itinerary. I immediately called customer service and just as other have said was put on hold for a long period of time. The customer service agents sound like they are from Southeast Asia and are difficult to understand. I told them I did not get the flights that I had selected but they were not willing to assist in changing them and said I could cancel the booking for a $75 fee! The CSR was not willing to help me and when I spoke with a "supervisor" she was also not willing to allow any changes and kept saying if would cost me $75 to cancel the booking or it would cost even more than that to change the flights. The "supervisor" was not helpful and hung up on me! This is a horrible website and Kayak should have nothing to do with them. Stay away from this website!
