As a Steam user I have transaction history for credits purchased and also for credits spent on “in-game purchases” - that is it. No itemized transaction history that would identify what those purchases were.
At this point the trail goes cold.
There is no record of the transaction at my xbox profile.
There is no record of these transactions at my microsoft profile (loginlive - where my other microsoft subscriptions are handled)
In effect then neither Asobo, Xbox/Microsoft are providing an itemized reciept/proof of purchase to the user.
There is a history of forum topics (some closed, some still open) where users have bought something in the marketplace and it has not appeared or it has later vanished. With no proof of purchase this puts them in an impossible position with regards any dispute with support.
