i think it could been hacked cause all my friends already had their accounts linked before i created mine 

Hey IamNdong​, do you think that your account may have been hacked by someone, or it simply the case that it was linked by mistake?

Can happen if playing together with friends, where you accidentally link the wrong account.

Let me know what you think may have happened and we will take it from there.
