Someone says I didn’t give item when I did, opens a dispute but idk what to do
You should record everything when you trade with buyer, for your security… If you have video showing his GT username or idk, name. And part of video when he accepts the item and trade is complete you are safe.
I did get a recording but idk where to put it
Upload the recording to a video site like YouTube and put the private link in the exchange chat messages.
