Another ebay rant -scam by buyer

I buy and sell on ebay , recently I had a buyer try and get a refund for a item not as advertised.

Tell me what you think here is the auction , buyer states that the item I shipped him is a heater delete plate.

I shipped the exact item I had pictured in the auction

Again I am the seller Dart-Swinger
