mobile

A month ago I was cancelling my home phone line and the Xfinity rep asked me to sign up for Xfinity mobile. I asked them if there was a way for me to test drive the network for free and i would make my decision after testing the network. They said yes i was able to do that and proceeded to send me a sim card for my phone to use. They also said i needed to add a second line for whatever reason and i said sure but I'm not going to use it unless i like the network. So i finally got the sim card and tested the network and it didn't work well around my work so decided to cancel it. So 12/6/24 I contacted Xfinity through chat and spoke with Suman and told him to cancel "BOTH" lines, and he assured me that "BOTH" lines were cancelled. So fast forward to today 1/4/25 I was on the Xfinity app and on the mobiles tab it says they were going to charge me $100 something dollars on 1/15/25 so i decided to go back on the chat and make sure i wasn't going to be charged. So i got connected to someone named Karan and they informed me that only 1 of the lines was cancelled and I would have to pay for the line that was left opened. I asked this person "Sayjal" if they could transfer me to a manager they said sure. 20 mins go by and I'm still waiting there, i finally ask "Still there" and now i get transferred to another person they said i got disconnected. So i tell this person the story and tell them to transfer me to a supervisor they say sure, and a min goes by and my WIFI cuts out randomly, (seems like they tried to disconnect me from them to not have to deal with me), luckily i was on my mobile phone. I let him know that I'm using my mobile phone and he said oh don't worry I'm not trying to disconnect you just stay on the line. Then I get transferred to someone, and they immediately end the chat and now I'm unable to get ahold of someone. Very Disappointed and would like someone from corporate to answer me this. Should I have to pay for the line when I clearly asked the rep to cancel the line and he assured me that he did and told me not to worry. Did your reps handle this situation correctly by disconnecting me from chat and making me unable to use the chat services? I have the transcript of todays conversation and the conversation of me cancelling the line on 12/6/24. Also I only used the line for less than a day just to see how it worked around my work, after that i did not use the line at all. Also I want to know if I'm blocked from Xfinity chat forever because I am unable to access it now after I tried speaking with a supervisor. Didn't get his name because he ended the chat immediately but it was something starting with an "M". Is this how you guys treat all your customers? Just disconnect them and hope they just stay quiet and just pay whatever fees you want us to?
