Hey there @elliethacker10
A game code is bound to a single account and can only be used once. In other words, that product code cannot be used a second time once it has been once registered by the original user. In other words, you got sold a void product.
The best bet you can do is to return the game and ask for a refund.
I am sorry for the situation and wish you luck trying to return the product.
For all I understand, no. Product codes are one-time use and are afterwards bound to the account it was used on. If you have a second hand game with the code already used, there isn't much one can do other than return the product.
You can contact the EA Support and ask an EA Advisor there if you want to get a clear as a day answer to it : https://help.ea.com/en/contact-us/
For more information how to contact the support, in case you want to give for example a call to them through VOIP : http://answers.ea.com/t5/Technical-Issues/How-to-contact-an-Advisor-via-EA-Help/td-p/5650100
Good luck !
