Arigatou gozaimashita

This is a past tense version of ありがとうございます Arigatou gozaimasu. This expression is used when you thank for something that has been done to you, for example, you can say it to your teacher at the end of a lesson, or to your host when you leave a house party. Also, the past tense version is the one to use when you write a Thank you letter.
