I went down a long odyssey recently of trying to get a refund for a food item that was four months expired the day it was delivered. Amazon refused. I escalated it. Amazon refused again. I tried to leave a bad review. Amazon deleted it. I reviewed the seller itself. Deleted again. Kept trying over and over again for several days, making ever so slight tweaks to conform to the policy. I came to the conclusion it was simply impossible to leave a negative piece of feedback.
