Extremely poor customer service

Over the last 24 hours I was assured by 3 Xfinity agents my phone service would be restored. I already knew I was ineligible for another repayment plan, but they said the higher ups and billing team approved me for August 15th because I was a valued customer. Skip to today. No service, refusal to let me speak to a supervisor through chat, and telling me there is nothing that can be done. So are the other agents just big ol liars? Did the new agent just not want to do extra work? What is going on? I can't even receive it make calls to try to reach someone on the phone, which was one of the agents suggestions last night if it wasn't fixed by 8am. I have screenshots of everytime I was told I was approved or when they said my service would be restored.
