If you have the message where he asked for a “friends & family” payment, I’d send it to the moderators. Not only is that against the rules here but also for PayPal. He’ll most likely get banned & whatever feedback he leaves you will be gone as well.
Also sounds like he was looking to make a quick buck through an interest free loan so to speak. Selling the same item multiple times. Definitely don’t need those type of people in here.
