Listen, I'm no fan of Ticketmaster but you should be very careful in your wording of a piece like this.
Although clearly opinion, it contains real slander and you should tread lightly. For example, "Which means that ticketmaster is purposefully delaying their efficiency in order to get people to purchase more expensive shipping times". This is the conclusion you came to but the company may be able to prove it has the delays for various other reasons. Because it's not a "fact", it's likely slander or defamation. The title is also problematic, "Ticketmaster is a horrible company". You might or might not be able to prove that as fact.
