Can’t access email for account password reset code

Trying to access my other online account for my Xfinity services (NOT email & NOT this account I’m posting from) and it says that my password needs to be reset. The email it wants to send the code to is one I no longer have access to. I’ve been to the Xfinity.com/password to try the reset as well and same exact option was given. There’s no secondary account recovery option set up and the cell phone number that is listed on the account is no longer active. Can’t get a live person on the chat because I’m unable to log in; the AI actually said “to speak to a live agent you need to log in to your account” and have not been able to reach an actual human via the phone number given by the AI and the pop up when trying to reset the password. I need an actual human who can quickly assist me with resetting this password as I have already spent the entirety of today on this and have got nowhere with it and this is extremely frustrating.

I always receive phenomenal support via the live chat option, but obviously that’s only when you can login to an account, and this is extremely frustrating and a huge disappointment and a far cry from the treatment and ease of problem solving that’s normally given to me by support. Makes no sense why they would put a limitation in place that will ultimately drive potential new customers away if they need assistance before having an active account, as well as anger and drive away the loyal customers they do have if they end up locked out of their account and need help from a human rather than a very poorly trained AI system. There’s not a single logical reason behind requiring someone to be logged into their account to access a human via chat.

Quick assistance with this matter would be greatly appreciated.
