I sold 2 months ago the priciest ring in my shop. I finished and shipped it in a hurry (the buyer needed it for a photo shoot) and 3 weeks after the buyer contacted me saying they didn't receive it, asking for a refund. I asked her to wait a week longer (in the end the parcels always show up), but she insisted that her shooting is in a few days only, and she needed the money to buy another ring. I refunded her, and she agreed if the ring eventually did show up, she'd repay me. The ring did show up, she picked it up at the post office (tracking info), but didn't repay me. Is there anything I can do?
I at least wanted to leave her negative feedback, to warn other sellers, but I'm worried she'd do the same thing to me, too, and I already have one negative from a same kind of buyer.
