avoid this company - useless, non-existent support

Do not use this company. They are useless and have the most clueless support I've ever encountered. I completed treatment weeks ago, ordered my retainers online, received an email saying "thanks for the order, you'll get a separate confirmation email soon" - the confirmation email never came. Since then I've talked to multiple agents over the phone, chat, email, all of them say the same thing - that someone will get back to me but no one ever does. I've forwarded the email and screenshots from my bank showing the charges and still no one is able to help me. Avoid this company and their useless, non-existent support, like the PLAGUE. I completely regret ever giving them a single dollar.
