Didn’t receive trade in envelope?

Hello

I have just got the iPhone 12 pro and part of the deal was I am meant to trade in my old iPhone XS. However when I got the parcel yesterday I didn’t get the trade in envelope. How or where do I request one? 
thank you 

P.s sorry if this is in the wrong section
