I was given the wrong tray for my invisalign, when I called to informed them, I was told to come back. I could not come back the same day because I have to go to work , so I informed them and I was told to pick it up the next day at 8am. I have to rush and cancel my prior commitments and when I went to the clinic at 8am, I was told if the tray that was given fits perfectly then you dont need the other trays. They are just wasting my time. Why you did not tell me this ahead of time!
