Query: wrong item in box

We ordered an RBC300 and received a box marked RBC300, however the item inside the box was an RBC100 - a much older model with a metal clasp instead of just the plastic clasp. We have returned this item and put a post it note on the box that the wrong item is in the box. I don't know if this is Amazon's error or Petsafe's.
