[AC Question]

There is one phone number that is calling me daily trying to get me to sign up for different things. I am tired and they are not removing me from their calling list.

Welcome to Android Central! You can use Verizon's feature to block a number for 90 days (but then you'd have to keep on adding the number): Usage Controls Manage Blocked Contacts | Verizon Wireless

An alternative is to add that number to your Contacts, then make select the contact, tap Menu, and make that contact always go to voicemail.

Go to your calling log. Long-press that number and see if "Add to Auto reject list" comes up. If it does, tap it. The phone will receive the call, but it won't ring. After a while they'll add your number to their "don't call" list just to stop wasting their own time.
