How do I disconnect my second phone number? I don’t need the service.
You just need to contact Verizon and ask them to disconnect the 2nd line. Hopefully they won't try to convince you to keep it like my old landline provider tried to do where I had to argue for 20 minutes with them before the representative finally caved.
We definitely want to help you out with your concerns. Is there an issue with your other line? ~Peter
