Titanfall Download on PC

I paid for Titanfall on the origin website using Paypal. When I try to download Titanfall on my computer, it said I needed origin. So I downloaded origin, and it said to get Titanfall, Navigate to the "My Games" tab in the Origin client, then click the "Ready To Download" button on the game you want to play. When I go to the "My Games" tab, there is no "Ready To Download" button. Where am I supposed to download the game? When I go to the store and find the game, it said "Add to Cart" as if I had never bought it. Can somebody please help me? I just want to download the game and not let $25 go to waste. Thanks, -Jordan.

Now, I realize that I needed the base game to buy the season pass. I'm an idiot. I thought the season pass was the game, but apparently it's not. Disregard all the other stuff I asked, now I just want to know how to get a refund. Is that possible? Anyone please help!!!
