DCL Gone

A couple of months back, all of my dcl disappeared. I originally bought most of them from the origin and some on the EA app. I logged in one day all traces that I ever had any packs are gone. The only thing left is my download history. Whenever I click on the game that is shown as downloaded, it takes me to purchase it again. I'm positive this is my same account. I have tried everything I can find online, and nothing works. Hundreds of dollars down the drain. I miss playing Sims. Please help!
