Am I overreacting?

So I bought this fandom collectible from a seller, and I received my parcel only to realize they sent me the wrong one. So I messaged them about it and I returned it the next day. They told me when they received what was supposed to be the package I was to receive and that they're happy to resell it to me when I'm ready or issue a refund. Told them I'd still love to buy it. They replied "okay, I'll make a private listing for you when you're ready". That was on the 19th.

Yesterday, I received my refund so I messaged them saying I'm ready to buy it and they replied saying "oh sorry someone else bought it when I relisted it"
