Xfinity Mobile agents have lied many times

So last month I reach out to a chat agent to see if there were any specials or promos that I could try to get before I switched to another carrier. After 30 minutes, and being transferred to multiple agents, I was told that my bill could be reduced to $20/line with no changes to my plan. I waited a few weeks and saw no change in my bill. 

I call and speak with an agent and explain the situation. The agent was nice, but flat our refused to honor the price stating it was an internet price, not a mobile price. They eventually offered to remove the $25 mobile fee for now longer having internet. I accepted since it was still a better deal than I could find elsewhere. 

Weeks pass again and I notice my bill still has not changed, so I went through chat again and was told that it would update by the second week or so of September. It did not update. 

I called and got passed around to 5 different agents before speaking with someone who was normal. They advised that the standalone fee could not be removed at all, but that i can call each month and get the fee waived/credited. 

Well I call and chat today just to be told that I am responsible for the fee yet again and they can't remove it. 

Why is it that every single time I speak with someone, they give me completely different information and act like I have never contacted Xfinity? I have been dealing with issues since April 2023 and can't keep doing this. I have a baby and a busy job, I can't keep taking hours of my time to explain situations that have been discussed in detail previously.  

Is there an escalation department or something where I can talk to someone to get an actual resolution?
