I was an establishing seller on their platform. I had 120 5-star sales interactions. Being an avid buyer, I made every effort to provide a buying experience I myself would appreciate, which included paying out of pocket for trackable shipping and including gifts. All this to say, I went above and beyond as a seller, and that included quality checks and inventory accuracy. Recently, a buyer purchased one of my most expensive products, a $65.00 collectible. As customary, I checked it, packaged it, and shipped it off with tracking. When the buyer received it however, they claimed they received a different style of the card, one that was only valued at $27.00. Now, for big shops with large inventories, mixing up styles and products is very common, but I am a casual personal seller and I’ve only ever owned one version, so it wasn’t a matter of mistaken inventory. I elevated the thread to TCG’s attention immediately because at this point the buyer was attempting to commit fraud. I recognize the company at this point would have to take into account both sides, as they sorted out the truth. My issue here is, they didn’t acknowledge a single bit of my evidence or testimony that this wasn’t a mix-up. I had witnesses to me owning the card, a history of 5-star sales, and I even scanned the card in their pricing app a month beforehand which they have a record of. I’m submitting this complaint because I shouldn’t be responsible for the loss in this situation. They receive 13% fees on every transaction and if they don’t want to be responsible here then they should create safeguards like picture confirmation to protect sellers and buyers alike. My view is that if they have some sort of 3-strike policy for a fraudulent buyer, how much more so should it be in place for hard-working sellers. I do feel it is their responsibility to cover this if they won’t do the work to sort out the actual truth. Thank you for your consideration. I am happy to elaborate further if needed.
