Hello RüdigerFärber,

Thank you for posting on the Xbox forums. We need a little more information to ensure we provide the correct solution. What is the error message that appears when you attempt to purchase

Xbox Live Gold? Are you attempting to use your Microsoft currency or a payment instrument to purchase the subscription? Are you attempting to complete the purchase on an Xbox One or Xbox 360? We suggest attempting to complete the purchase for the subscription
on our website. The link we provided will take you to a section of our website where you can make the purchase. Be sure to let us know the results!

His information is correct. It's per the terms and conditions of the offer -

Hey mate, I found this on the FAQ:

I renewed my Xbox Live Gold membership and I didn't get my Rewards Credits. Why?

Credits for renewing your Xbox Live Gold membership will appear on your MyRewards page within 2 days of your current Xbox Live Gold membership ending and the new one beginning. In addition, if you allow your Xbox Live Gold membership to expire before you
renew your Xbox Live Gold membership, you will be ineligible for this offer.

It is not possible to purchase Xbox Live Gold using Microsoft account funds. You will need a valid payment method (debit/credit card, Paypal, or some other service in your region) or you will need to add a prepaid Xbox Live Gold membership card.

Translating to Italian using bing.com/translate:

Non è possibile acquistare Xbox Live Gold utilizzando i fondi account Microsoft. Avrai bisogno di un metodo di pagamento valido (carta di credito, PayPal o altro servizio nella tua regione) oppure dovrai aggiungere una tessera di abbonamento Xbox Live Gold
prepagata.

The free month with gold membership is a trial period and doesn't offers all the privileges of the paid gold membership. I suggest you to purchase xbox live gold membership to enjoy the full privileges of this membership.
