Cant' create a new account !

Without finding out from you what happens when you try to create a new account, no one will be able to offer you a reasonable answer.

Have you tried the link that is shown in the message? It's the best place to begin, you will find links to your part of the world and at the end of that process, if you require it, the option to Get Support, by phone, chat or email.

There is one thing for you to consider though; if you have managed to sign into Apple in order to start this discussion, then you already have an Apple account, so do you have a specific need to create a new one? If you create a second account, you will not be able to use media (songs etc.) purchased on the first account.

In that case you need to go to the website mentioned in the message and follow the steps through to the Get Support option. I've put the link in this post (the blue text), although you will see that it states Choose your country or region - Official Apple Support which is correct.

It's the page where you choose the region of the world that applies to you.
