I've returned a part of my order, but in my account, it still says that I need to make the full payment.

Returns are first processed by the online or physical store. Once processed, the store will inform us of the return and we will update your payment status. As such, the payment status isn’t updated automatically. In fact, it may take a few days to update after the return has been processed. But don’t worry, we’ll let you know as soon as we’ve updated your payment status.

If your payment status has not been updated after one week, email us at info.de@zinia.com or speak with us via the Zinia chat during our customer service hours (Monday to Friday: 9:00 a.m. - 5:00 p.m.).
