No one works there?

I have been trying to contact travelstart from the moment I received my confirmation email on the 21st. You sit for hours on the line and no one answers, I have sent emails and contacted them on Facebook. Nothing. The dates were not booked correctly and I don't see how I could book a flight a week before I even arrive there. I am reaching the end here? You give 24hours for changes but no one answers the phone?????
