Did you have a fomal contract with the moving company? If not, you should send the company a certified letter explaining that you will pursue legal action, if the items are not delivered within thirty days.
If you do not receive a response within the thirty day deadline, you can file a complaint with the local court (called the "Magisterial District Judge") which has jurisdiction on claims up to $12,000.00.
Finally, you have the option of hiring an attorney to assist you in this regard. However, it all depends on the amount at issue on whether it makes sense for counsel to be retained.
This answer is for informational purposes only and does not in anyway constitute and/or form an attorney-client relationship.
File a lawsuit against the company where they are incorporated or in your home area. Contact the attorney generals office consumer fraud division and the d.a. officecin your county and file a private criminal complaint. You can also contact the united states attorneys office. Conduct your own investigation on the internet. Then write them a lettdr with all of the contacts you made. If tjst doesn't make them want to make you happy then they have committed possibly serious frauds against you and others.
