Who I have the same questioned this topic

Hi, I disconnected my service and was told that Verizon would mail me a shipping kit so I could return the 5G modem. I never received this kit and multiple conversations with Customer Support have told me either Verizon doesn't' send out return kits, Verizon cannot send out a kit because my account is now disconnected, or that I can pay for my own shipping back to Verizon. I even took my modem and hardware to the Verizon store and they did not accept it. 

Is there any way I can get this return shipping kit? Does it even exist?
