Despite careful checks by our editorial staff, it is possible for parts of the e-bookto be missing (e.g. attachments, interviews, illustrations). If there is not an explicit comment in the free preview of the work or in the product information that these parts are not included in the scope of delivery already, we will immediately write the author and ask to send it once again. You will, then, receive the full version as soon as possible.

If it is not possible to deliver it at a later date, we will, of course, cancel your order completely. Just send us the invoice of your purches via e-mail to [email protected] and indicate the reason for your complaint.
