Long story short, I purchased a PSA 10 Pikachu ex 276 from a seller, only to find out after the fact that the same card, same cert, same pics was sold 2 other times within hours, one of which on a different seller account. Immediately after purchase, the seller marked it as shipped untracked, so I can't do anything cancel-wise. I called eBay, and they said the seller was in good standing (with 0 seller reviews) and they didn't see anything suspicious (even though the seller already had a duplicate sale that they could obviously see on their end), so they couldn't do anything. My question is, this is obviously fraudulent, so why is eBay customer support refusing to do anything?
