Chat Agent Changed my XFINITY Plan without authorization

As I have seen other places in this forum, I have been scammed by a chat agent while seeking help. I was trying to seek a refund for a $10 XFINITY NOW Wifi Pass that I did not mean to renew for another month. When I asked the agent about this, the agent said he/she would "credit me $30 for being a loyal customer". When I said I was just looking for the specific transaction to be refunded, I was asked for my email address, after which I shortly lost internet and was presented with an order confirmation in my email. This agent cancelled my 1GIG plan and started a new 2GIG plan at an increased rate with no ability for me to cancel it in the portal. The live agent chat then showed a new agent after I reconnected, who was equally as unresponsive and unhelpful. I eventually got on call with live support, who was able to provide slightly better assist me and move me back towards a plan that was more in line with what I had previously. However, I now fear that my account is in an weird state, as XFINITY app shows the new plan, but the XFINITY website still shows the unauthorized plan that the agent created.

This all spawned from a simple ask to have a $10 charge removed, and I have spent near the last hour chasing down a way to stop the fires of a live agent representing XFINITY performing fraud on the live chat.

I should like to get in touch with Xfinity's fraud / customer support department to report this occurrence and figure out why this is not a one-off occurrence on this forum, as well as ensure my account is fixed.
