This company is unethical and probably illegal. I understand no refund policies, but when salespeople recommend inappropriate products, and an MD isn't the one who sees you, and then you have adverse side effects ethical companies would stop treatment and refund (yes, I know that's a run on sentence).
Do not use this company. They will not refund for services not rendered...even if they caused or are aware of defective equipment, services or damage caused by their services. I am permanently scarred and have been shocked by their machines. They are terrible people and they work for a horrible company.
