Hi. I recently sold an intangible item. Questions now here; The user is unregistered. Can they still file a dispute? What’s the day limits? And what are the chances of them winning if they sent 3 payments in total for an intangible item they already received? Just want to know as I feel like this person may try to chargeback on me (they assured me they were using prepaid funds and prepaid funds cannot be charged back) after receiving intangible items. Anyway I can win disputes like this? Thank you.
