[reereestore]

Please can someone help I sent a very expensive Pokemon card at first the buyer said they received it no problems and sent pics with my envelope in the background along with card in condition I posted it in perfect ! I was like Ur welcome good doing business........then 2day later they sent a message saying they looked back on card and noticed damage ?? Then they sent a series of pics of damaged cards I said you already sent pics of card received and it's as I sent perfect condition he reakns no the light was hitting the damage .wen I said that's not my card and I want a video of front and back ...because I know he's keeping the card so obviously he isn't going to damage it and I know that he wldnt be able to show me that as proof he keep excusing and excusing then after deleting more messages because I kept pointing out look that's not my card he just decided to to an item not described.fast forward he sends a 20c energy card leaves me a bad review. I of course opened a case immediately the eBay agent looked thru everything and confirmed they cld clearly see this is a scammer and I would receive full refund and case closed . But hours later after also confirming on chat I get an automated message in messages saying case closed buyer refunded ???? Wat is going on I'm in tears it's a 700 pound card guys . I rang up just now they said they r going by the automated message please help
