You can waste a lot of your time by contacting them, and asking for supervisor after supervisor - as I recall, your time is pretty valuable, so you may need some other motivation...
- if you do this, then do it ALL in writing; that will be slow and they will try to get you to call them (to waste more of your time and prevent a "paper trail")
- try to find their fax number, then you will have a written receipt showing they received your complaint

You can file a complaint with your state's regulatory body, but I will bet that not much happens.

President Obama attempted to set up a federal regulatory body to take care of such problems, but the opposition party in Congress has defunded it to prevent any effective regulation.

Your only other recourse would be to hire an attorney, but that will not be cost-effective.

I would write them or fax them and if it ever happened again, at least make sure the state has your complaint on record. It may have been mere incompetence, but there are many, many areas where controls are supposed to be in place to catch mistakes.
