Can't login to my other account through official site

[Ratatatouille]

Greetings,

 

I can access this account on both the launcher and the NCSoft official site while I can access my other account through the launcher but NOT through the NCSoft/Bns official site.
I wanted to change the email of my other account but now,I can't because of this.
I've logged out of this account before trying to log in the other and I also remember trying this months ago and same thing happened.
When I try to log in my other account through whether NCSoft site login or Blade and Soul site login,it says something like "error!Something went wrong on our end".
It's probably worth mentioning that my other account got hacked/hijacked a year or 2 ago but was retrieved by NCSoft/bns support who helped me change its email and password back then to keep it protected.

 

Anyone knows how to solve this problem,please?

I have already submit a ticket but thought I'd ask here as well,in case there is something I can do myself to fix it because,I'm really confused,at the moment.
