How can you change someone's ticket and traveling plan without confirming the change with your customer? That's just WRONG. First they changed my uncles' flight and didn't send them confirmation/update/notification email. And they change their international flight. They got a meeting to go to, customer's schedule is not something that cheap air can decide. And to get the schedule back to what it was, they want to charge my uncles $200 per person. You kidding?! You changed the the flight (no body asked you to), ruined the schedule, to ask you to change to back is good enough for you, and you ask for money for your own mistake? That's not reasonable at all.
