I had a Tw octane on rocket league and this person said that he would buy it off me, I’m new to game flip so he explained to me what it is, he told me to list the tw octane on the auction for £100 and he told me to look in the comments and I could see that he had bought the item so I gave it him and he just ran off with it and didn’t pay me, is there any way I can get the money or my item back?? his Xbox gamer tag is Cofsi, please help thanks
How Gameflip works for Rocket League items is that the buyer pays on the site first, then you are notified in the Notifications page and https://gameflip.com/listings/sold of your sold item, not the comment section which are written by other users. After seeing that your item is in the Sold tab, go in game and trade with the user (you may ask them for the order number to verify they are the right person). Then you can rate the buyer to complete the transaction.
What happened in your case is that the scammer simply told you they paid for the item, and you believed it at face value. Please read the guides https://gameflip.zendesk.com/hc/en-us/articles/115004730347-How-to-sell-a-Rocket-League-item so this doesn’t happen to you again.
