C&C Tiberian Twilight - Unable to Redeem Code

U answer on my email question in a second time in edit it, I write an answer to u after reading the original massage.

This is not a chat so, try to give accurate and complete answers, not editing previous messages with add important info later, when there is an active correspondence.

Most people have many email accounts. Many quickly create them in order to do something quickly and then immediately forget the password to it or the entire account (they do not need it), and so it can be repeated many times ...
I don’t know how else to help you. Try in the EA support chat to give the key to the game, the purchase screen and ask to give you the email to which this key is attached, at least in the form some like x***x@gmail.com, maybe this will help.

Also, I find similar topics for info:

@TERORISTU Hey, we want to help you, but it is a difficult problem you're having. Especially because we ourselves can't look-up information about the game-key. And yes @MADrag0n is talking a bit in circles and asking multiple questions multiple time, which can be annoying, but it really seems you have activated the key before with another account. If you say you absolutely didn't, then there is something weird going on. Sorry that we can't really help you any further; we're just limited by what we can do ourselves.

Btw, next time with a problem: try to provide more detailed information about the error etc. from the beginning 🙂 Avoids a lot of questions :P And I don't know why @MADrag0n Is advising against message-editing as it prevents message-spamming in a thread.... @TERORISTU Can you keep us updated when you talk with EA and Steam again and tell us what they told you?

1. In this transaction, as I understand it, Steam acts as an intermediary, like any other key store, he just sold you the key. At this stage, EA does not know anything about this. EA enters the case only if someone activates the key code on an existing EA account. We have two events: a) receiving a key from Steam and b) entering a key in EA account. What happens between them, neither Steam nor EA can say. Different people can participate in event a) and event b). We can believe you, but not Steam and not EA. In such situations, by default, Steam and EA blame the person who bought the key in Steam. Of course there are exceptions ..

2. We see that you bought a game pack consisting of
"C&C: RA3",
"C&C: RA3 Uprising",
"C&C 4: Tiberium Twilight",
"C&C: Kane's Wrath",
"C&C: Tiberium Wars".
You said that u can play all other "C&C" games from the pack without any problems, only this one ("C&C 4: Tiberium Twilight") has a problem. I do not have one of these games in Steam and I don’t know the details of how the key is activated in the EA account for them. I see that for this problematic game, before going online, you need to activate the key in the EA account. What happens to the rest of the games in the pack? Is it really only one game from the pack requires such actions?
We see that on your EA account there is not a single "C&C" game. I can’t understand how this can be if you say that the other four games from the pack are working fine.
@TERORISTU , @mrtnptrs  Can you clarify this question for me.

@MADrag0nIt is very likely that games activated via Steam/indirectly via EA account, don't show up on Origin as they aren't Origin-games. It isn't like if you buy the Steam version of them you also get access to the Origin-versions of these games. So, they won't be listed on Origin. Btw, I told you this already haha.

@TERORISTUIt is indeed very hard for other people to tell if you are lying or not. We believe you, but others may not. EA giving you the name of the account to which the key is coupled, could probably be your only solution in this matter.

Edit: it seems to be a widespread old problem that was never fixed:

Etc.

There doesn't seem to be a good solution.... and they will never update the game to fix it: the game was received very badly and the developer has been closed-down by EA for years.

@mrtnptrs  It is not an answer. If some game require EA account to play it its mean 100% u have this game on that EA account and u can see it in games library.

@MADrag0n Isn't it logic that if you don't own a game on Origin itself, that it won't show up in your Origin library? Having a game on Origin isn't the same as having a key coupled to your EA-account. He doesn't own the Ultimate Collection.... Origin was even released more than 1 year after CNC4 was released on Steam, so it is to assume of course that it wasn't integrated into Origin. Do you think @TERORISTU is lying or what? With the proof of purchase he showed us and the fact many people have these problems, I think it is safe to assume he isn't manipulating us. I really thought @TERORISTU was to blame (like having another account, actually not owning the game etc.), but I'm starting to think EA and Steam are here at fault.

EA should be able to provide him with the username to which the key is coupled; if there even is one, as it could also be that this is all caused by a bug... It doesn't matter that EA is not responsible, but they are well able to help him with finding out WHY the key seems to have already been redeemed.
