Selling a target gift card

So I just sold a 50$ target gift card and this guy buys my giftcard for 39$ I send him the number and access number and it was going well. He then says he tryed buying a gift card with the gift card I gave him and now is complaining how he already used the card and is not going to pay me my money. He is trying to scam me and im scared and do not know what to do

If someone buys your item you should get a notification about it. Do not send anything before that.

Create the ticket here, send the evidence you have about the code. Wait for further instructions by Support.
