Dear Sir or Madam，
I'm Li Hua， an exchange student here in New Zealand．

I booked an 8-day holiday to Australia in your agency last week． But now I am sorry to tell you that I must cancel my booking．
I was really looking forward to enjoying the holiday． However， I was informed this morning that I would not be able to take those days off as planned． I have to attend an activity held by my school to raise money for the poor， which can really help them a lot． I do apologize for not letting you know earlier． I hope this will not cause you any problems．
Besides， I would be very grateful if you could let me know whether I can get my deposit back at your earliest convenience．
