Hi I need to register Sims 2 on Origin.
On this Official EA article (https://help.ea.com/article/redeem-your-serial-code-in-origin#2) it says that it is possible by contacting an EA 'Game Advisor' via Email, Phone or Chat. After extensive searching on many EA sites. I have not come across a single Email address or option to live chat (I have found a number to call).
Pick the callback option, the three times I did it, they were phoning me within five minutes.
