I saw the Admob have sent a postal mail to my adress, the problem is that I wrote a wrong adress.
I have read that I have to click “Resend the postal mail” but I don’t have this button, what can I make?
You will need to wait wait for 4 weeks to re-apply pin. After 4 weeks you should get that re-apply button.

Thank you ! 
Just an advise: check the process in the adsense site - Google AdSense – Website monetarisieren und Einnahmen erzielen - since the admob site is kind of a “mirror” of the info displayed in the adsense site.
It happened to me too and I got the letter in a week.
