What can we do to get the moving company to deliver our furniture as soon as possible?

We are in the process of moving and our items were loaded onto a company's moving truck on Friday June 27. Our items were contracted to be delivered by no later than Monday July 7 and are still not here. Through contact with the company, we have been told that they do not have a driver for our materials and today they let slip that our items have been removed from the truck and placed in a storage facility without our knowledge and/or permission. Is this legal? And also can we just request that they subcontract the job out to a different moving company since they can't seem to get it together? We are furniture-less in a home with two children and working parents so anything that would help get our stuff here as soon as possible would be wonderful. Thank you for your help.
