I reported all this online at www.BBB.com, www.ftc.gov and I googled the Attorney General of Texas. Each place has a tool for on-line reporting. They definitely need to be held accountable. I imagine they are still taking orders. collecting money and NOT fulfilling orders. I finally had to go to Camping World to get the brackets and wiring done. I hope you can get some resolution from this. I've given up hope.
I noticed they removed their physical address from their website. If you need it here it is:
Roadmaster-Tow-Bars.com
2600 E Southlake Blvd Suite 120-292
