My new NFS Unbound purchase went to waste because of some unknown reason.

I bought my NFS Unbound in a sale this year through steam , thinking I will enjoy the game I used to play in my childhood. As I was away from my system, my friend tried to play the game, so he opened it from steam. When asked to connect to an EA account he created a new account with a temp email thinking the he wouldn't want to hinder my progress with my email.

Now later , when I came back and tried playing , I got the message that my account has been banned. I first thought my original EA account has been banned, but later got to know some other EA account is connected to my steam and it has been banned.

I found this later that it was him who tried to play but couldn't, it seems EA has banned the account because it was created using a temp mail. Now , that email is destroyed and there is no way to access it and unlink from my steam account. I mailed to EA support and its been a while but I got no response about this situation. I mailed with the attachments of the purchase as well. I also made an appeal to unban the account.

But as per my logic, if temp mails are supposed to be banned or they are not allowed , EA shouldn't let us create an account with such unknown origin emails only or at least warn the user. Also, I have no idea why exactly it is banned , I am just guessing that this could be the reason.

Banned EA account ID: zelslayer669

I can log into it , when I start the game, otherwise I cannot. Let me know if anyone have any suggestions on what I should do.
