Hi im new to gameflip but I purchased a rocket league(steam) item about 4 days ago when the guy had posted the listing 30 minutes prior with (online) in his name. I messaged him with all my info saying im ready to trade and he responded saying he would be home in 10-12 hours, he then marked the item as shipped. From then I messaged with him back and forth for 3 days until finally opening a dispute to stop the auto rate timer. Now that we have finally be able to talk online with each other, he keeps insisting that I drop the dispute before we trade, however looking online I am not sure that I will be able to reopen the dispute if I do indeed close it. What should I do and also what kind of evidence will I be able to capture to protect myself from a possible scam going on.
