Doctor threw out tray number 1 and accidentally gave me the attachment template. How should I handle this?

Dr. Threw out Tray Number 1 and Accidently Gave Me the Attachment Template. I knew something wasn't right! I've been wearing what I thought was tray number one for two weeks only to discover that it was actually the attachment template! They must have thrown out tray one and given me the template to wear. So mad! When I put on tray two the pain was out of this world. Now looking at my trays they all have the letter 'N' on the bottom except for that one which has a letter "T" for template! Waste of 2 weeks and my money for that tray. How should I handle this? Can my treatment be ruined now? I'm doing express so I only have ten trays and one was thrown out!
