I just thought I'd post this to see if anyone else is having/did have the same problem as me.
I'm in the UK and I bought FFXIII the day it came out, I went onto the square enix members site and registered there and put in the code that came with my game and registered that. But I never received the 20 digit promo code. I figured that I'd given them enough time for them to send me one (1 month) and still not having received anything, I finally contacted support.
I got a mail back saying that they were very back logged with sending codes out and if I still hadn't got one by now that I should send them my details and the code and they would look into it. Unfortunately, I didn't keep the code as I thought that once I had registered it, that would be it (more fool me I guess). I explained all this and am now waiting to hear back.
My point to this is, has anyone else (UK people) not received their promo code yet. The uk site seems unfinished, its not like the na site, all you can do is log in and see what games you've registered and change your settings and stuff and I wondered if this might be whats holding things up, or have any of you got your codes already?
