In need of a Trade in Kit because one was not send with new Macbook Pro

Last week I received my new M4 Max Macbook pro and I was hoping to trade in my old Macbook. I believe that I went through the process correctly and requested the trade-in kit. I entered the serial number and everything to get the value on my old Macbook. However, when the new Macbook arrived, there was no trade-in kit with it. Its now been close to a week since receiving my new Macbook and I have not received the kit in the mail. Is there a way to get the trade-in kit sent separately? From what I gathered from the page, the kit is the only way to trade in by mail, but I did not see a way to get it sent. Is that correct? Is there a way to check if I did request the trade-in kit correctly, and if I did not do that correctly, can I still get the kit sent? Thanks!
