Explanation of the trade: customer requested 1.15B in OSRS GP across 2 different trades. Payment method was CashApp. The first trade customer sent $130 on Nov 5th and the 2nd trade customer sent $400 on Nov 8th 2021.
How they scammed: After a few days the customer requested a charge back through his bank for his CashApp payment and so Lucas my partner messaged him requesting he pay us back for the $530. Customer stated it must have been a mistake but never returned the payment.
