Anyone ever heard of this happening before......?

I live in some apartments and have a garage, well some new people just moved in the apartments and they gave them a garage, only problem was.. it was my garage. I only keep a few tools and boxes in there, but went to park inside yesterday and it was full of someones elses stuff, i mean up to the ceiling, motorcycles, tires, washing machines, boxes i could barley walk inside, and now my tools are buried under everything. The apartments say they cant move everything out til the weekend. Now cant work without my tools...
