I offered to trade my code for Inversus for the PS4 with Killer909 for his No Man's Sky code for the same console. Yesterday, he accepted the trade provided if I went first. So I gave him the code but told me to hold on to it until he gets home. Today, I checked the code and it seems that he used it but I have not received my end of the trade yet. Tried to contact him and he hasn't responded. Did I get ripped off? What should I do?
