i finally got the code from my 3rd party company. i think the company didn't expect a third code after i lodge a customer service, but they sent me the code anyway afterward .very glad its all over. but still, im expecting an apology from square enix for delaying this code. they should've just send the full access code and the square enix registeration code together, not seperately and at different day, making people confuse. Really gave me a headache.

Hope this news prove useful for somebody.
