Hi Ccarr25, thank you for reaching out to Xfinity Mobile through the Forum. I am sorry to hear you are having such trouble trying to get your phone number changed. This is not the experience we want any of our customers to go through.
I will be happy to help you get this taken care of for you, If you would like to proceed please send me a private message with the following information; your first and last name, the full address for your residential service, the last 4 digits of the store payment method on file, and finally, your current mobile number. I look forward to hearing from you.
