Who handles counterfeit toy story merchandise complaints?

The evidence supplied includes a general description of Amazon, a major online retailer, and a brief mention that Toy Story is a known entity. No part of the Amazon article refers to a specific entity or process for handling complaints about counterfeit Toy Story merchandise. Because the sources do not mention Disney, Pixar, or any other company in this context, we cannot identify a responsible party based on the verified information. Therefore, we do not have enough evidence to answer the question definitively.
