Hi, rh29174. Thanks for posting here in the community! Normally you would receive an email with a tracking number once the order ships. Have you happened to receive that email by now? If you're still looking for support on the modem shipment, please feel free to send me a PM with your first and last name so I can take a look at your account for you!
I am glad that you were able to fix the issue. I apologize for the experience. We know how important our customer's time is so we always strive to help as soon as we can. If you have any other questions me or our team here on the forums, please feel free to reach out!
Thanks for being a valued Comcast customer, @rh29174.
