@its-Cheyy Just to clarify, the reason you don't see Batuu as an option is because you're running the Legacy Edition of Sims 4. All new packs released after October 2019 are incompatible with the Legacy Edition and won't load even if they're installed.
So yes, you should ask for a refund, but you'll need to specifically say that your computer runs the LE and therefore can't run the Star Wars pack. Since packs are normally not eligible for refunds, it's important to be specific on why you can't use the pack.
Or, if you're not sure whether your computer can in fact run the standard version of Sims 4, please run a dxdiag and attach it to a post.
