Welcome to the forum. It's good to read the posts from breeders that appear here, because all your suggestions and information is welcome to all of us non-breeders.
I agree with the others that this is not a common practice among BCOA breeders. I am sorry that this happened to you and yes, you should get your deposit back.
Welcome and kudos to you for helping with rescues! It sounds like Kowboy was a great introuction to the breed. I'm sorry for your loss of him and Indy. this is a great place to share and keep memories alive. I'll keep my fingers crossed for a speedy relocation back to your family in CA!
