Trying to charge me more

I have been on the phone and on the app with 7 people today that will not fix xfinity's own mistake. And now I finally get a supervisor but she is saying that I have to pay the past due amount for my phone line on my account which per the contract shouldn't even be there because they [Edited: "Language"] up in the first place. They said that once the past due has been paid they will give me what my contacts says i was post to get in the first place. I have paid my bill besides that one always on time and up to day every month. But because they [Edited: "Language"] up I have to pay more money. How is this far. I think I will talk to a lawyer if this isn't fixed and my phone isnt turned back on. Oh did I mention that I have been dealing with this for over 2 months now and I only signed up for the bundle on 8/8/24. The first time I spoke to a supervisor they turned back on my phone saying that it shouldn't even been turned off in the first place and they will have it fixed. However, after the first time fixing it they turned it off a month later. I called again they fixed it pretty fast and apologized. Then again they turn it off today and say that I have to pay more money to get the contract that I was already post to have. Oh and I took screen shots of my contract and confirmation of what I am to get on my service by the life agent that signed me up as well.
