I've been trying to get in contact with Support about this issue since the Steam launch and have yet to see any help/results here on the forums or after ~two support mails sent. Am figuring in (my case it least) either the distribution outright failed, they disappeared due to something from the account link process, or I grabbed them from the Visiphone during a server connection issue/desync and they got eaten by the void even though it looked on my client like I got them successfully.
Between stuff I earned disappearing with no explanation and now around half a month of no response from support, I'm very disinclined making any cash purchases and risk it failing & taking my money or my items evaporating again with no hope of a Support response in sight were things to go wrong.
