Definition: You are provided with a user review of a restaurant. Your task is to classify the given review into two categories: 1) positive, and 2) negative based on its content.
Input: I placed an order via delivery.com, then waited...and waited. After an hour and a half, I tried calling--no answer, and a full voice mail box. I've been trying to get through now for more than 2 hours, and still no food or even anyone picking up the phone. Ridiculous.
