EA Refund Tool & Contact Us Option Not Working

Yesterday, 12/4/2025, my sister wanted to get almost all the Sims 4 expansion packs/content packs/etc. We bought them (totaling almost $500) but they unfortunately aren't compatible with her laptop. I've tried every single route recommended to try and get a refund for these, but the refund tool won't work now, and when I go to the "Contact Us" form, it says "this issue isn't supported by our advisors". 

I'm refusing to let this go for purchases that are unusable and totaling over $500!!! Someone please help me here.
