I have never in my life been treated so poorly

Reluctantly,  I returned to Xfinity in December and the sales guy was really good. I mean good to the point where he totally sold me wolf tickets. The thing that baffles my mind is the lies were not even necessary.  Xfinity is the only internet provider in my area and so I had to sign up.  Your customer commitment statement says, that you fix your wrong however I have NOT experienced this.  Over the past month I have called and spent countless hours on the phone without resolution.  I have been told that my issue can be fixed and then told it cannot be fixed and the only solution provided was for me to spend more money.  But today was the straw that broke the camel's back.  While on the phone with a representative and she was rude and of course offered no real solution.  I asked to speak with a supervisor which I request every time I call and was advised that it would be a 3-4 hour wait.  I say okay, I will wait.  while sitting there I decide to hang up and call back instead of waiting on a silent line. While making the call my phone loses service.  SHE CANCELLED MY LINE....SHE CANCELLED MY LINE.  I did not request this, she did this on her own.  SHE CANCELLED MY line ~ I am still in shock.  I live alone and this is my only personal phone ....SHE CANCELLED MY LINE.  Thank goodness I have my computer which has a work line on it and so I call Xfinity and speak with another rep for 2 hours only to be told that she cannot help me because I was not meeting her halfway. Ma'am you all cancelled my line, and my internet connection is faulty because of issues with my Xfinity connection, and you can't help me because everything you suggest doesn't work and it's my fault. UGHHH.... I asked for a supervisor and was told I could not speak to one but one would call me back if I would like... CALLL ME ON WHAT LINE. SHE CANCELLED MY LINE.  But from Xfinity's perspective it's my fault, the paying customer who has been repeatedly lied to and disrespected. ughhhh.  I have never ever experienced anything like this in my life.  And to be told over and over that my concerns cannot be escalated is absolutely ridiculous.  I will make time to post reviews everywhere until Xfinity rights this extremely egregious wrong.   SHE CANCELLED MY LINE and the next lady said, it is my fault that she can't help me find a resolution because I am not doing enough on my end..... I am beyond confused and I want to speak to someone about alllllll of the drama I have encountered.  Wait did you read what i said, SHE CANCELLED MY LINE!! ughhhh.
