Hi @Jasmin1
With the help of Google translate, my understanding is that you wish to delete the SaaS trial you have started.
All trials will expire in 30 days from the starting day unless you pay for them. If you haven't paid, they will be expired already.
If you want to delete the tenant and data inside them, then please reach out to our Customer Support team who can assist on this.
