@donasmrs-- That's a good question.
It's a good idea to report to local and state agencies first. I went to the consumer protection agency in my area. I think that's a good place to go to first. Better Business Bureaus are another good agency to go to initially. These are not government agencies, they are non-profits but they can help resolve problems between businesses and consumers.
If you can't get results with local or state agencies, then you should proceed to national agencies like national consumer agencies and trade associations.
Also, you can file a complaint with multiple agencies at the same time. So if you want, you can file a complaint both locally and nationally. Another option is contacting the media like local radios and newspapers. They can be very influential.
