Question about Dreame L20 Ultra Complete

I was so looking forward to today's delivery, it said that 10 units had been ordered and I had a delivery date of 28 January and then 23 January, but now they suddenly say that the part is out of stock: I wonder how serious Galaxus is about this. But now they suddenly have 10 of the other version without extras, which suddenly costs 200 more. It's annoying!
