I bought some Pokémon Prismatic Evolutions Surprise Boxes back in January, and as many people know, scalpers made stock extremely limited in the TCG in the last year. So, I contacted the seller about my items not being dispatched yet, and they explained they were having trouble getting stock, which I understood was happening to all sellers, large or small, so I said I was fine to wait a bit longer. After a few weeks I messaged again, and got a similar response regarding stock. Now I've been messaging the seller and they aren't responding to me at all.
Obviously, the buyer's protection period has expired and I don't know what to do. I contacted eBay customer service and was basically told all I could do was keep messaging the seller.
Is there any other advice? Any help would be greatly appreciated.
