Do not send by mail if AH requested
Received the half through the AH as requested, then the second half was forgotten and sent the next day but by in game mail, which is not acceptable, i requested through AH for security reasons toward blizzard, and you are compromising this security by sending by email. Not the first time it happens. Other than that, golds received very fast and reactive customer service. just please respect the channel through which it has been requested for delivery.
