Unable to locate modem package

I recently signed up for the xfinity internet service but never got a follow-up email containing the tracking/shipping information for the modem package that comes with the plan. After checking in with a live agent, I was told that the package had been delivered on Sep 10th, but I was unable to locate the package despite checking multiple times throughout the days afterwards. I had tried to contact another live agent to see if there was a drop-off image of where the package was left in case it was hidden from sight, but they told me to reach out to BRINGG for the package details instead. I did not receive any tracking links or communication about the delivery, so I cannot access the package details and despite what I've been told, BRINGG does not have a customer service line. I need to set up wifi for my home as soon as possible, is there a way to get a replacement modem package?
