Hey guys, i got banned for ever yes i saw the topic although that person in a way scammed me i asked for $60 SHE SENT ME $40 TRYING TO GET IT CHEAP i said no after she sent although i stated somewhere i do NOT refund anyone if they sent me the wrong amount ITS UP TO THEM TO GET IT BACK NOT ME, now i understand she did get ripped off and some way what although she new she sent me the wrong amount and she wasn't going to get a refund SHE HAD TO GET IT BACK, even though she scammed the $40 herself as she told me by scamming steam accounts i do think i should atleast get a temp ban since ALL my feedback is positive, like c'mon guys i admit i did rip her off but she had what was coming after i lowered the price all the way to $60(accounts worth $150+) and she sent me $40 trying to get it cheap i wouldn't budge that, thanks.
