I signed up to move my Comcast service, and with it, I got a new plan featuring a phone. I found a randomized phone number I really liked, but the page timed out, and when I went back to register over again, the phone number didn't show. Does anyone know how I may be able to get it switched to the original one? I have the number copied and pasted. Is there any way for me to change my own phone number? Thanks.
