As you have had your server for less than 14 days
As you have had your server for less than 14 days, you can cancel it with immediate effect as per our Terms and Conditions.
If you have received an invoice for your server, you will automatically be granted a refund for the billed amount.
Please note that the server will be taken offline from the moment of cancellation and will no longer be accessible.
hetzner太帖心了，搞的我都不敢取消了，等过了14天再取消？怕把帐号搞没了。
PS，目前帐号上十多台机器，很少14天内取消机器。
