Merged account without concent

On 8/24/26, my son and I visited an Xfinity store. In front of the sales representative, my son explicitly requested his account be canceled. The representative stated she would take care of it. Instead, she left the account active, resulting in 3 months of unauthorized, past-due billing on a service that should have been closed. Furthermore, this same representative merged my account with my boyfriend's account without formal authorization. I demand that Xfinity honor the cancellation date, completely wipe out my son's fraudulent past-due balance, remove any negative credit reporting, and un-link my account from my boyfriend's."
