Definition: In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.
Input: I bought the product based on its advertising. After one year, I found it did nothing described. When I called to stop auto-delivery and return the product, the person answering the phone was offended and responded rudely. He wanted to know why I was cancelling and was argumentative. He also said they did not guarantee the product and did not accept returns. Fortunately, I bought it through Amazon. I will never again buy a Relentless Improvement product.

The marketed description of this product is meaningless.
