Starter package lost in mail

I signed up for Xfinity last week and ordered the starter pack with router and equipment. When I check the tracking status, it says it was delivered 2 days ago but I never received it. Usps didn't have any picture or anything for me to verify the delivery. I submitted a claim on USPS to report it, but how do I receive a replacement starter kit? I need a router to get it set up and don't want to pay another 30 for it when it was lost in the mail or stolen before I could get it. How do I get another starter kit sent?
