Sold a fortnite account around Jan 19th with the help of playerUP MM and everything went smoothly as the buyer was pretty responsive. post sale, i was waiting for payment as usual it took more than 1-96 hours like it was mentionmed but i knew it was gonna take longer. 6+ months gone now and im yet to get my payment. they say they have some "bank issue" thats why they are unable to process the payment. they asked for any alternate payment methods and i mentioned i accept crypto payments but no response from MM. Crypto payments dont need any bank etc so idk why im still not being paid. its mentioned on PlayeruP that they do crypto payments
i loved PlayuerUP but ive lost faith in them at this point
