Accept the return and see if the buyer who claimed non-receipt sends it back to you. That is about the only way to determine if he indeed got it. (It could have been stolen off his porch which is not your responsibility.). If he sends nothing back, you will not be forced to refund. But if you continue down the i-won’t-cooperate path, you will lose your item and the funds. It is your choice.
You sold an expensive item without knowing the policies that can affect a sale here. That is on you, @doucas-15 . On eBay, it is the seller who accepts the risk of selling here. Not the buyer, not eBay.
In addition, you have allowed your feelings to enter into a business transaction and it has been to your detriment. You created this mess. You must now undo it and it’s gonna cost you. How much it’s gonna cost you remains to be seen.
By the way, miscalculation of shipping costs can happen to new sellers still in the learning curve. Don’t beat yourself up over it, but realize it is your obligation to absorb the cost. Again—not the buyer’s or eBay’s.
Selling on eBay is fraught with issues that can trip up sellers who are unprepared. Better start reading the rules and policies that govern the site if you decide to continue here. I’d recommend starting small to prevent such a costly mistake occurring again. Best of luck to you.
