Live Xfinity agent lied and told me my bill was extended but while in the middle of working from home my services were interrupted

On Tuesday I spoke to a live Xfinity agent via chat on the app and told him my situation that my bill was due on Thursday and that I need an extension until Saturday. He said  he'd see what he could do and he came back and told me that he could have extended it until Saturday the day that I get paid, and that the services will not be interrupted ,and not to stress and worry about anything. Today while I was working from home my services cut out in the middle of me working even though I was told that it would not be interrupted. I have  screenshots proving what he said to me ,and on the date that he said it to me and what date I could pay the past due balance. I could have figured out some type of way to get the past due balance paid if I was told there was no option but I was lulled into a false sense of security, and now I possibly could get fired. I talked to two agents and they both told me the same thing, that there's nothing they can do unless I pay the balance on my account. I need someone to reach out and rectify this situation.
