Me and and another PayPal customer are having issues receiving money. I sent John Mayor an iPhone X and he sent me $***. My account said it was pending until he confirmed the package. He then confirmed it and it said my account had to be expanded. John then sent me $*** to expand my account but he was not very detailed in explaining what I had to do. He wanted me to spend $*** cash, which I don't have, to purchase steam cards and that's where the issue came in. I thought that he would sent the $*** to my account so my account can clear and I would then purchase the cards with his $*** and send them to him, unfortunately that was not the case, and now he thinks I wanna scam him out of $*** when I do not wish to do that. I do not have any money from this transaction but he has the iphoneX that I sent him in perfectly good condition. I just want my account to clear so I can recieve my payment. You guys can sent him his $*** back from my account, I just want my payment. Please give me a call back, I've been waiting all week for this payment and it's becoming frustrating.
