Re: sims 4 code already been redeemed??
You shouldn't need to re-enter your game code again, as you have already registered your game through Origin and should be ready to download and install.
You will need to make sure you are using the same Origin account you either bought the game with or registered it to. Go to Games Library and click on Sims 4 to download.
If you've already tried the above, you need to contact EA's Customer Service, as it sounds like it might be an account issue that we can't help with.
1. Click on the following link: https://help.ea.com/en/contact-us/ (once there make sure that your country is correctly selected in top left hand corner of Help.EA.com)
2. Find the affected game - in this case select either Origin or Sims 4
3. Select your platform
4. Select topic and issue.
5. Select a contact option. Please note that available contact options do depend on your country settings, time of day and the topic/issue you choose.
