On the kick off video they said that we must tell first if our team is missing any parts before midnight on Wednesday, but we will not be getting ours until Thursday or Friday what are we supposed to do about this?
I haven’t seen anything in the documentation so far dealing with such a situation. What you should do to be safe is contact FIRST directly and explain your situation. I am quite sure they are aware of the possibily of similar situations and have provisions for this.
Ok what is the best way to contact first with this problem?
Not by email 
Check out this page on their site:
