There's a bug in the refund section where the option to refund skins or champions is there even though you have no refunds left, but you can't actually refund them and it will say Unable To Purchase Item: Unknown Error.
Post your PBE bug reports here: something not functioning as intended? Store is broken? A champion's ability is not working? etc
