filing a complaint against a mail order company?

[fabsroman]

I would complain to the Attorney General in your own state. Every state has something called the Long Arm Statute, so if it was something significant you could even hire an attorney and attempt to sue the vendor in your state unless you agreed to "Terms and Conditions" on the sale that would require you to sue in the vendor's state. Best bet is to contact your Attorney General and see what advice that office is willing to offer.

You can also file a complaint with the Better Business Bureau if the vendor is registered with the BBB. That will let other people know about the ethics of this mail order company.

If you used a credit card for the purchase, call your credit card company and dispute the charge.

Ultimately, I would need to know more facts about what happened to give you some more avenues of pursuit.

Mind you, the advice above is coming from a "shyster" attorney and your attorney general is a "shyster" attorney too. The vendor might even have "shyster" attorneys working for it. So, you might as well get a "shyster" attorney on your side too.
