Need some help regarding school book problem

[ps2cho]

Ok basically I signed up for summer school on the first day I was able to (so I could get the schedule I wanted).

So I signed up for a research methods psych class with a teacher who's ratemyprofessor ratings were good.

So, a month later (a week before class starts) I get an email from another professor saying "Welcome to the class blah blah" and I was like.... "I don't remember that being the teachers name??"

So I was informed of the book I needed.....of course....different from the one listed originally!!!

So basically the school switched teachers without informing me and now I am stuck with a $50 book that is worth $8 now so I can't even get close to getting my money back for it.

Should I peruse the school over this? What do you guys think?
