I need help correcting the mobile number associated with my Xfinity ID.

I need help correcting the mobile number associated with my Xfinity ID.

Xfinity is incorrectly treating my landline as my Xfinity ID mobile/security number. When I try to change it to my actual mobile number, I get the error: “Mobile Number is already linked to an active account.”

I checked Account → Xfinity ID and Security → Your Accounts → Manage and Link Accounts. There are no linked accounts.

I need Xfinity Support to correct this existing mobile-number association so that my actual mobile number is the security number for this Xfinity ID. I do not want my landline used for security verification.

Please have an Xfinity Support representative assist me. I can provide my account information privately if needed.
