<human>: Could you distill the essence of the text into 1-3 sentences?

Okay I don't know where to ask anymore. 

Here's the story. I left Canada to attend my friends wedding that's gonna be on the 14th as I'll be his best-man. Being the good friend that I am I went despite me having school. Now originally I planned to stay a month from Oct. 1 to Nov. 1 knowing that I'll be enrolling January 2013. But when I already bought my ticket the profs said there'll be no enrolment for January 2013. So here I am shortening my trip by 2 weeks.

I considered cancelling my ticket but they're cutting back too much like 20% of the ticket price + $150 on top of it (my ticket is $1100). I said okay, I'll just reschedule my flight then so they did. I have a flight from Manila to Taipei but my flight back to Toronto is still on the waiting list til today, and it's been 5 months, it's not even peak season! 

The airline (Eva Air) constantly says that my flight for the 15th is still on the waiting list. My family called the agent I bought the ticket from and she said that if I will pay $500 she'll do something (which is disgusting). The weird thing is that before I left for Manila I went and visited their office at Toronto and the lady said they still have 40 seats! 

So here I am asking for help if someone could negotiate for me. Someone who works maybe on an airline company. I really have to get back to college as I'll be missing a lot of work. I'm doing my projects here and sending them to my classmates as it is but 3 more weeks will be too much.
<bot>: Wait-listed for about 5 months now. It's not even peak season. Need to get out of Manila by the 15th to 18th.
