New contract - Services NOT what was promised and HOURS wasted trying to work with the service center. REPS cannot help me! Please help!

I have been a full-services, loyal customer for over 11 years (since April, 2012).  A few weeks ago I noticed my bill had shot up quite a bit due to my contract ending. After a few calls to see if I could get a deal for an acceptible amount, I finally got an agent named Luis.  Luis promised me the same services (NO changes) for about the same amount.  I took his word for it and confirmed the link he sent me to my phone.  After really thanking him and hanging up, I got the confirmation.  There were many services cancelled, AND, my bill went up about $50.  I was fuming mad.  To me this seems like a complete "bait and switch" that he pulled. Then I noticed my DVR had erased about 90% of my recordings I really wanted to keep due to you folks putting me on a much lower DVR storage plan.  And then I noticed my HBO and Showtime channels disappeared.  This is only what I noticed.  I have not checked all the channels yet.  Since then, I have placed numerous calls to your service center, and nobody knows how to help me.  Nobody is taking ownership of this.  I have had many calls disconnected while waiting for help, and so far 2 supervisors have not called me back despite promising to do so.  I have wasted countless hours waiting around for a call back, and on the phone.  This is an epic fail if I have ever encountered one.   Please, Please, PLEASE help me here.  I cannot believe your company would do this to a longtime customer that paid his bill on time EVERY month for the past 11+ years!  Please reach out to me ASAP and get this mess cleaned up.
