Please understand if the phone is not answered because we are dealing with technical issues or are on another line with a different customer. Please leave your callback request including contact details and, if applicable, your user number. Also briefly state what the matter is so we can prepare. Give us some time. We are not a million‑customer company and do not use call centers. We will respond in any case and as promptly as possible (depending on the issue), or within 24–72 hours, especially on weekends (including Mondays, as many customer inquiries accumulate here due to the weekend backlog). Thank you for your understanding!
