Vanguard Relocation Services Lost jewelry and clothing Portland Oregon

Northwest Relocation (set up through Vanguard Relocation Services) picked up my household goods from WA to be delivered to TN.  My household goods were delivered minus two (2) boxes.  The following day I notified the moving truck driver, via text message on his cell phone, that two (2) of my boxes were missing.  I hoped that if they were still on the truck he would put them aside.  One of the boxes contained jewelry and the other name brand clothing.  I also notified my contact at Vanguard, who I set up my move through, of the missing boxes.  I was told they would try to locate the boxes and to file a claim.  A few days later, I was informed one (1) of my boxes was found.  Upon delivery of what they thought was one of my boxes I discovered that it was not one of my missing boxes but, instead a box of dirty towels! On several occasions I notified the moving company representative that the box was not mine and asked how he would like me to return the box.  To date, the moving company has not responded. On numerous occasions and to no avail I have tried to contact them on the status of locating my boxes and returning the box that does not belong to me. The moving company’s lack of effort/communication regarding the return of the box that is not mine, confirms their complete unprofessionalism in the attempt to locate my two missing boxes and general business practices.  The representatives no longer respond to my emails regarding what steps they have taken or are taking to locate my two boxes.   As referenced earlier the two boxes that were not delivered contained jewelry and expensive clothing.  Vanguard states on their website that they are committed to top level customer satisfaction. They clearly have not tried to meet a minimum standard of customer satisfaction.
