Her question was "How do I get them to reverse this charge?"
If you filed a complaint already with the BBB and your state attorney general office, then work with them on resolution. That's pretty much all you can do. I have had success in the past with just the BBB complaint.
You can also dispute the charge with your credit card company if that is how you paid, stop any future payments via your bank. But, getting a satisfactory resolution is in your best interest since you likely don't want your credit damaged.
