Question about be quiet! Straight Power 11 Platinum

Need to know why the German Galaxus page has a delivery date of 04.11 to 06.11 and the Swiss Digitec page says "delivery date will be updated" ? (As of 03.11.2020 14:45h) At the same time, I would like to ask why I still receive a letter on 27.10. stating that my delivery date remains unchanged, but nothing is delivered. Not even another email that it doesn't work.
