JustFly will steal your $ if you make a change!

Don't book with JustFly!!!! I tried changing my travel dates because I needed to shorten my trip - it made me cancel my flight for flight credit ($150 charge), now that I've been trying to rebook, the cheapest option is another $200 and it keeps saying flights are unavailable, try again later. The next option is another $502 on top of my original $500 flight! They don't respond to my emails, customer service is in India, they've stolen $650 from me and there is no way of getting it back now! TOTAL SCAM!
