Justfly.com zero is a TOTAL scam. One of their customer representatives totally misrepresented their fees when I had to cancel flights, telling me that it would only cost $225 to cancel three flights and that we would be able to use the remaining airfare credit within a year. I have her on video/audio tape saying it. Then when I went to rebook the flights, all of a sudden, there is an additional $600 fee. After many calls and multiple attempts to discuss the false communication with managers, the representatives were rude, unhelpful and one literally hung up on me. One told me that their representatives don't see the additional fees when customers have to cancel. It was absolutely the WORST customer service I have ever received! I am calling the BBB and posting on every social media outlet I can find. Their website speaks of integrity... they don't have any! I'm a teacher and single mom trying to take her two kids to see their aunt in Florida. I would never have canceled the flight if I had known it would cost an additional $825 because I can't afford it! I am horrified that this company exists and treats their customers this way. Do NOT use them!
