These are customers/ users at risk of churning and a large portion of them will not buy from you again, probably because you they are not really satisfied with the experience.
Address immediate issues that they highlight in their feedback and follow up to dig deeper if they did not leave a comment.
In the example above, you can see that Peter Griffin was totally disappointed with his last order and he gave a score of 1 with the short explanation, "Really bad service. Never buying again."
The thing that you can do is just ask him, "What we can do better?" or "Tell us more about your poor customer experience."
