Transfer Out Pin - We Are Unable To Authenticate Your Device

I’m leaving T-Mobile to Verizon because it’s significantly cheaper. However, my lines are unable to receive calls and instead are sent directly to voicemail because the port process has not completed yet. It’s not complete because Verizon needs a transfer pin. I open the T-Life app/Account/Settings/Permissions&Controls/TransferPin. The transfer pin doesn’t generate because it’s unable to authenticate my device. Can the store fix this issue or are my lines stuck in perpetual limbo? Going to assume this needs to be escalated to higher tier management and not a team member. This is infuriating. Any ideas what to do?
