Tokyo Express Moving Co LTD — international moving company does not deliver as promised!

We paid over 1 million yen to the CEO, Mr. Ueno Kazuhiro of Tokyo Express Co LTD Moving Company to ship my family's household goods from Yokosuaka, Japan to Maryland, United States. They packed and shipped a 40 ft container of our belongings and delivered it to WSI Van Lines, US Company in Gardena, CA. Our household goods was scheduled to be delivered on April 15, 2017. We were informed that Mr. Ueno Kazuhiro did not pay WSI Van Line Moving Company in US. WSI Van Line Moving Company refuses to deliver our household goods. The company including myself have reached out to Mr. Ueno numerous times by phone and email and he does not answer. He promises to pay, but he doesn't. We learned that 3 other families are in the exact same situation. Our household goods have been on hold for over a month and we are still trying to figure out what to do.
