thats unlucky mate

same happened to me before xmas except mine moved towards me at the other side of the car before it wedged into the sill

made me move very quickly and after that i went out and got a trolley jack and now have axle stands to

i learnt the hard way

tbh i dont even jack the car up with it when i'm at home i use a trolley jack although mines not as bad as yours i touched mine in with some spare paint i have for a temporary measure but having read the post i see its been mentioned about R32 skirts

that was the thought i had at the weekend

as it will cover the sill damage and the money it would cost to repair my sill i can put toward pait/skirts

so could work out ok hope you get sorted mate
