Why can not I change the country setting for my account?

I am an Adobe user living in Korea.

CS5 product was registered and used

I tried to use the Photography plan this time, but I could not make a payment due to the country setting.

I contacted Adobe Korea, but told me that I need to register a new ID, and that the photos in my current account's cloud should be upload after the backup

It's a waste of time to re-upload photos already exists to an new account

I do not know why my country  does not change because I have an already exists account .

So when I asked if I should contact the US headquarters, she told me bluntly to ask head office.

and more angry things was she said to me could not change the country of my account in Adobe Korea.

I would have just contacted the US headquarters if I had a guide in the first place,

but I wasted my time.

I want to pay my current account, without want to rejoin.

and I do not have time and time to move pictures

Please solve this problem by all means.
