In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.

The first shipment ("Subscribe & Save") was very good. Arrived in a timely manner and was good. The second monthly shipment came in with both jars of mayonnaise separated (oil and other ingredients) and no amount of shaking and shaking and refrigerating would make it stay mixed and firm up. The seals appeared to be good. We didn't open them to try it. Something wasn't right. They both stayed in a very liquid form. Never had mayonnaise do that and bad mayo can kill you. Amazon made it easy to get my refund and did not want me to return the jars (thank God).
Mayonnaise Looked Bad (Separated and Liquid) Upon Delivery
