Add ons vanishing

So, today I finally reopened the sims as I was ready to return to my world and hyperfixate on it for the week. When I realized that my Vampire add on was missing. I purchased this March 5th, 2025  at full price and played with it for a week before getting off. When I first got on today I thought maybe it was just not showing up since I had to re login and update the game. So I logged out again and still nothing. Okay weird right? I decided to just try to open my Sims world anyways and see if it was just a bug or glitch. It was not. It says I cannot open my Sims world without the Vampire add on or else it may not even function. Okay great let me see if I just need to redownload it or whatever. No, EA is trying to make me purchase it AGAIN. I checked my transaction history and what do you know there is no transaction but they make sure the free add on transactions are still there. I took it upon myself to do some research as well as talk to a representative via chat. They did not help at all. I even pulled up my bank account transaction history and there is literal proof that it was in fact purchased. So here I am again purchasing the Vampire add on so I can access my world. After this I am not giving any more money to EA. They are so selfish and money hungry for no **bleep** reason.
