Hello Nunokouto. Thank you for reply.
My issue is that the account is made in Germany and that's why it requires me to add personal data number, from an German ID card. The paymet will be on paypall so I have that. I've read on internet that I should buy the 12 year code from amazon because the PS plus is asking me for the personal data to have the 14 days free trial. :(
It might be that my ps account is linked to facebook or maybe I've inserted a different age when I've made the account? Which doesn't match my collegue datas? Thank you again
