Hi, this does sound like a frustrating situation.

From what you’ve explained, it looks like the buyer may be trying to get a partial refund after already getting a discount. Things like saying the item is in “too good condition” or “too heavy” don’t really sound like valid reasons for it being not as described.

The best thing you can do is stay calm and keep everything within eBay’s process. I wouldn’t offer any partial refund outside the system. If the buyer genuinely thinks there’s an issue, they should open an official return request so everything is properly documented.

As it went through GSP, eBay usually handles these situations and sellers are often protected.

If they want to return it, let them go through the proper process. If they dont open a case, then it likely means they’re just trying there luck to get some money back.
