Platinum Founders items not showing?

So, i purchased the bronze pack through steam a few days ago and had fun playing the game and decided to purchase the platinum pack yesterday evening before getting off for the night. i have just logged into the game and got some of the platinum items, but i have not received the majority of the things that came with the platinum pack. I have not received the Cerberus mount, the armor, the locomotive, or skin (did get the helm though).
