I changed the phone number on my acct saved it but the website asked for a second number so I entered same number again but it doesnt change anything still showing old phone number
Unfortunately, the system won't allow you to use the same phone number twice when asking for an alternate phone number on the website. I can review your account on my end to see if I'm able to confirm the number update to your phone number. If you'd like me to do so, send me a private message verifying your first and last name, the phone number, street address including city state and zip code, and the account number or phone number associated with your services.
To send a private message click on my name "ComcastChe", then click private message me.
