Oi, that is an entirely justifiable "no". Even booking a parking suspension in front of your house for a moving van might require more notice than that! They are being idiots.
So sorry you are still in suspense and feeling down, Mmmmcheese. Would it help a bit if you "gave up on" Christmas and planned a really good Twelfth Night? I tried to shift the "Christmas period" last year, as I'd been intending to do for ages, especially given that part of DH's family is Orthodox, so their Christmas is on 7 January, making our 12th night coincide with their Xmas Eve (annoyingly, they have taken to celebrating St Nicholas - on 19 December, but the dual-calendar Xmas does mean something). DS got a choc for each day of Christmas, and we kept the tree lit throughout the period. 12th night (Jan 6) this year is a Friday, so you could have people round for mulled wine, mince pies, satsumas and singing - the best bits of Christmas, without all the grimness (arguments, nothing being open, etc.). All the Christmas stuff will be discounted, too, so you can gorge yourselves on chocolate log for tuppence!
Oh, dear, figgy, that doesn't sound very festive!
Now, mopsy, you stop all that cleaning! Maybe looking at all the disorder and accepting it will serve as a form of childbirth-control, which will enable you to write your chapter and dry your hair!
