In a Shellnut, this company will help you to spend more money on your tickets. If you book tickets with them, it is very likely a 'customer service' will call you and offer 'help'. Do not trust them, they are liars!
Please also check the other's comments, you will know what gonna happen to you. Also, how it is possible that the Overall Rating distribution is such extreme if their employees didn't try to influence the results.
Anyway, just don't book the tickets with them, Period!
