It's 2020 and I'm still buying stuff from the sims 3 store

I bought 1000 sim points over the weekend, bought two things to complete sets, and I think I got double-charged, because the web browser glitched, I refreshed, and now I have the items I bought twice in my purchase history. I talked to tech support and they were unable to help me. So I have about 300 points left and I dunno what to do with them yet.
