Re: School Fundraiser - did I get ripped off?
I agree, talk to the school. It's ultimately their responsibility because the mother in charge was acting as an agent of the school. And they should have records of who bought what. I'd call her again, if she blows you off again then go to the principal. I'd also write a letter of complaint of how this is being handled and send it to the school board, mail it with signature confirmation.
I'd also let them know that you will not be supporting their fundraisers anymore because they clearly think it's okay to steal from you.
