I've seen a good body guy bring back metal that looked like an accordian, so yours should be fixable. If you have insurance, it should be covered under the comprehensive because it was in no way your fault.
Report it to the police, and make mention of the moving company. Talk to some of your neighbors and see if they know noticed what moving company it was, and if anyone saw anything. Most people won't come forward, but they will tell you if you ask.
