On my Verizon account, there are 2 phones (a1 - my phone (account owner), a2 (old phone number (Samsung) was released by Verizon and new phone added (Apple) to plan and become the latest phone on the plan ) on plan A, 1 phone (b1) on plan B.
When I try to schedule an appointment at Verizon store, Step 1 - (a) logon in to my Verizon account (username, pwd). (b) Verizon system 2FA (2 factor authentication ) calls either a2 and b1. I want 2FA to call a1 and b1 instead.
Whom in Verizon tech support should I contact such that 2FA call a1 or b1.
