What the hell?

So I have gotten like 4 games from the give aways yesterday on Origin. And I logged off the account with the 4 new games to go to another account. But when I did that and today I wanted to play one of those games, I log in to the account and the games are just gone? It shows that I have no games at all. What is this?

Are you sure you logged into the right account? if so, then you will have to contact support and tell them the keys and they will assist you, also, check your email, maybe payments used to get these keys weren't completed

I've gotten the keys from the giveaways.. And yeah I put all the email adresses I have into Origin and not any account has it..
