Can't confirm delayed internet equipment shipment date or billing start date for new service

I recently signed up for new internet service and chose the delayed equipment shipment option for my equipment, since I won't have access to my new home until late August. I have two concerns I'm hoping someone can help me verify:

1. Delayed shipment date: My account and my order confirmation email do not show any ship date or delivery date for my equipment. I'd like to confirm the delayed ship date is correctly set and that the modem won't ship early to an address I can't receive mail at yet, or too late.

2. Billing/service start date: I want to make sure my billing start date is aligned with my move-in date and that I won't be charged for service or equipment before then.

I'd appreciate it if someone could help me confirm both of these. I understand I may need to move to a direct message to share my account details privately. Thanks!
