What people ignore is fact that as far as business goes, Square Enix is shit. This was an example.

Well here's the thought process.
buy from NA for NA. EU for EU and JP for JP
HOWEVER.
NA/EU server list in same thing.
Why would a NA/EU code not work for both since its going on the same server.
Adding on, why would they then not offer to EXCHANGE the code. Make EU code unusable and give you a NA code. Since NA is sold out, this would create another subscriber and another source of income for the company, instead of what this representative did.

Basically HORRID rep. He could have gotten another subscriber and business for his company by doing something simple. There loss. With all the errors for login. And now the lag and delay compatibility error created from the new 10 hour maintenance patch... i'm currently about to cut my losses pretty soon.
