Hello there!  Thanks so much for taking the time to reach out to Comcast Business Support here in our Community Forum.  We are so glad to hear from you and want to assist in any way that we can today.  No worries!  You have reached out to the right team and we are going to get you squared away.  So that we can get this ball rolling for you, please feel free to shoot us a private message with your name, business name and complete service address.  That way we can access your account and get started.  

You are going to want to send the message to "Comcast Business" so that it goes into our queue to be responded to.  😉
