One of my buyers asked for a refund "extra shipping" because someone came to deliver a package and said there was "postage-due." The buyer is asking me to refund the excess shipping but this looks like someone was scamming the buyer. The "postage-due" was basically a post-it note with a stamp of "postage-due" and a handwritten amount. Plus the person making the delivery took payment in cash ! Has anyone else had a buyer get put into this situation ?
