How does it work/how long does it take to get a tray replaced? Will I have to pay for it since it wasn't my fault? (photo)

Part of my new Invisalign tray is bent. I was about to start tray 3 of my Invisalign, but when I pulled it out of the package part of one of the teeth moldings was folded over. I tried to put it in and it kind of fit but definitely did not feel 100%. I am concerned about this extending my treatment too much.  I left a message with my dentist and am waiting to hear back.
