Yes, as others have said, it doesn't matter how cheap they are, they are not worth it.
I booked a flight to Paris through them and decided to pay more for the shortest trip possible. One of my connecting flights was canceled and I was automatically assigned a new flight, suddenly I'm stuck with a 6 hour layover... not what I paid for. There were other flights with similar lay overs and cost about $200 less. On top of that it takes off when I need to be at work.
Worst customer service ever, they didn't care about the extra money I spend, my time wasted or that the new flight simply did not work. They emailed me saying that we could work out a better flight schedule but once I finally talked to someone they basically told me I had to take it or leave it and that there were no refunds.
They also hung up on me twice forcing me to wait for over 4 hours on the phone just to get through to talk to a person.
They are the worst! Never again
