I called to order replacement 3rd set of aligners. They reset my app to reflect that a new set was being mailed out. Later on that day, I canceled the order because I found the aligners and I asked them to kindly return the app back to the correct point so I can track my progress correctly. 3 weeks and the app still says I haven't received my aligners and that they're being custome made🤦🏾. Cmon guys! The aligners are working great! Don't mess it up with simple errors that can be fixed easily.
