After routine cleaning,he took ~1hr to check my teeth + impressions.I canceled the AM after via phone + came in personally that same AM for a non-Invisalign appt & so I reiterated my decision.He said he'll tend to it later since he'll be out of town that wkend. 4 wks later, he asks me again if I want to continue.I still said "No"(never had anything Invisalign-related after that first impressions-taking).He then said that I have to pay $1500 for the impressions & a "lab fee" that was charged him.
