My sims 4 pack didn't come with a code
I bought a sims 4 university pack, and it never came with a code. It was a disk.
If it was a brand new game and not second hand you may be able to provide the receipt to EA and see if they are willing to help you but they are under no obligation to: the same applies to the store you brought it from.
If it was a second hand game then there is nothing you can do: you should have checked and dealt with it within a reasonable amount of time after you purchased it from the shop.
Unfortunately due to the amount of time that has passed it is unlikely anything is going to happen regarding this issue.
