Everything from my boxes is just gone!

Hello, Yesterday the 11.05.2018 I bought a new apartment in the city for 650 thousand and was also very happy about it. I have everything from my old tent in my new way vacated and today because 12.05.2018 are all the boxes of me empty! And I had such good stuff! Can I somehow get my stuff back because I had wingsuits and net launchers and so many other goodies! PLSS!! I have the house 344 everything is out of my boxes !!! Try it yourself otherwise because I have no photo, etc. as a proof, because who thinks that the next day so everything is gone ...
