Why can't seller's leave negative feedback for buyers? I've had several who have purchased & simply don't pay or reply to messages. Thanks

I have had several buyers simply not pay & never reply to emails. This is so wrong & a waste of my time. Why can't sellers leave negative feedback for these buyers? it's not fair. Can't be bothered setting up a dispute most of the time. What is the best action to take? Thanks.
