Disgusting service

If I could give them a zero star I would. I have been trying to change a time sensitive flight for the last 2 days but as I can't speak to an agent I am unable to get a new flight amended quickly. Any mails take hours to receive a response. If you want a straight forward flight with no alterations this system works. However, if you are looking at possibly changing dates, etc don't consider using them as you can't under any circumstances speak to someone.
