How do I leave negative feedback to a non paying buyer who does not answer my emails

Buyers cannot have any Negative Feedback or Comments. Just Cancel the Sale after 4 days, using "Buyer Did Not Pay". Your Seller Fees will then be Credited back to your Account. The Non Payer then receives a Non Payment Strike and you can Relist.
