Hey @Rusty69,
Welcome to our Community 
The Voicemail isn't one of the add-ons that can be managed on your online account, especially if it's included as a feature in your current plan. To have the Voicemail removed, you need to speak to an agent through customer service and they'll be able to help.
You can reach us here or we can send you a private message on the community, let us know what you prefer!
