PS - I don't know what's worse, these d-bags or the scammy buyers. I just fought off a second case in less than three months:

• Buyer buys your item
• eBay account is tied to one person, PayPal account another person, shipping address a 3rd person
• They hold your item for a couple of days/weeks, then email claiming "defect" and asking 30-40% refund and they'll go away, else report you and leave bad feedback, usually with totally BS claims
• For me, every time, the buyer is in the New England area and has East African or Middle Eastern names

I just had this happen again on a lot of iPhones I sold recently. My process for testing refurb electronics is more rigorous than any vendor whose products I refurb (Dell, Apple, HP etc.) and I don't send out "iffy" products.

I've found that, in most cases, adding a restocking fee to your auction and replying to tell them "please note there is a restocking fee, ship back the item in the EXACT condition it was received" leads to them closing the return request promptly, but ... still. FFS, it's annoying as hell.

I've started reporting buyers for abusing the returns system. I'm over it. It's straight-up hostile to buy and sell these days.
