Definition: You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Input: I ordered the Teenie pack of Greenies that was supposed to come with 96 teenie sized chews. I ended up receiving a pack with 52 teenie sized chews and 8 large chews. I returned the product because I did not receive what I ordered. Amazon couldn't replace my order because they couldn't guarantee I would get the right product if ordered again.
Output:
Negative
