Query: I never received the juggling balls.

I ordered the juggling balls a few months ago to teach my new 4 month old puppy how to catch things in her mouth. At the same time I ordered clickers to teach her clicker training. Since that time she has been successfully clicker trained. As for the balls I never received them. So I can rate the seller as terrible since I paid for something I never got.
