Bought Sims 4 expansion pack twice, yet does not appear in library?

I just bought the businesses & hobbies expansion of Sims 4, yet the game is not appearing in my library or in game? I tried to buy it once with one of my cards, and then again with another card, and neither have worked despite having full balances. And I did receive the pop up of the successful purchase on both times. What should I do in this case?? Is this something that's been happening recently frequently or? How can I get a refund for one of those purchases??
