It's been three weeks since Verizon took our money for new phones and still nothing to show for it. No indications on the website or when making the purchase that these particular phones were on back order. No updates since then in support. It took Verizon an hour+ on chat to confirm the order had been completed in December, then they said it would ship January 7, but that deadline has come and gone.
As of today still no indication in the online shop that these phones (iphone 13) are not available to ship immediately.
If something isn't going to ship immediately just say so, allow customers to reserve and make payment when it's available, notify of changes in shipping date by text or email.
Bottom line: if you need to replace a phone quickly don't rely on the Verizon website or customer service to give you reliable information.
