Live Agent LIED and Xfinity doesn’t care at all to correct.

Yesterday 4/24 I had an installment plan payment due and had to reach out to Xfinity to ask if I could extend until 4/29 when I got paid. The agent said they would look into it and came back and said it was extended. Then even suggested they could help lower my bill and set me up with a new plan. I left the interaction feeling glad Xfinity was so easy to work with. Then I wake this morning and my internet is disconnected. I call in and explain the situation and the agent replied verbatim the same exact thing to every one of my statements- “unfortunately due to your broke installment agreement we can not restore service without a payment.” The issue is, the arrangement wouldn’t have been broken had I known the agent was lying about the extension! I ask to speak with a supervisor and the supervisor does the exact same thing as the previous agent. I explained that I have the downloaded transcript and that my chat history in the app still shows the conversation where the agent confirmed TWICE that I had an extension. When I go back to look now the chats from yesterday are GONE while every other chat I ever had remains. Thai God j took screenshots and downloaded the transcripts. I am so frustrated. There has to be something that can be done about businesses like this and I might be mad enough at the moment to commit to figuring out what I can do.
