I am writing because I can't order another line on my xfinity mobile account online. I don't know why I can't when all of the customer agents I have talked to for the last 6 days have told me that everything is fine. I ordered 2 lines back in November and i am trying to add a 3rd and it continuously tells me that the website is unavailable and to check back. The customer care agents get the same error and can't figure it out. What is going on and why is my account the only one doing this?
