Lied to about service package

I have been a customer since 1991 and have gone through many changes in plans and services with Comcast.  This time I have been lied to and in my opinion cheated.  I have had the X1 Prefered Double Play for many years and have been satisfied completely.  I called because I was having lag time on my internet and was told that I needed a new modem because my speed was slow.  It turned out the lag time was due to my keyboard but at the time I did not know this.  I was then told that my package was old and was going to be discontinued and that I would have to change to a new package.  It turned out that this was all a lie.  My old modem was just fine and there was no discontinue date noted for my package.  I was told that the channels I watched most of the time were all included in the new package.  I was also told that the modem would cost me 4 dollars extra.  This was not true either.  I specifically told the lady that I would purchase my own but she said that the modem came with the package and there was no rental price.  But now I am paying and extra 18 dollars.  This is not including the price hike which I already knew about.  She assured me that my channels were in the new package.  NOT TRUE.  I lost National Geographic Wild, AHC, Smithsonian, POP, Reelz, Vice, Sundance, and SCI.  Not to mention the movie channel extra.  Now it is a garbage Xumo which is garbage.  I also gained a total of 41 sports channels including 32 Hockey Games!  I do not watch any sports as I am not interested.  The modem has made absolutely no difference, I have lost the channels that I watch the most, and am paying more for sports which I never asked for and was assured that I would not get.  And by the way, why do I need 50 Music stations.  If I want to listen to music, I will listen to the radio.  Yes, I am a senior and yes, my preferences are more educational.  I enjoy history, animal shows, science, and old movies but I know I am not the only person out there with those tastes.  And now you cheat me out of programs that I watched because you want me to pay more for the PRIVILEGE of watching those shows.  The customer service of Xfinity is sorely lacking in honesty, the costs are way to high, and the technical service leaves something to be desired but I have stuck with Comcast for over 32 years.  I think that that is about to change.  I do not mind paying for a service that delivers a good product but I do not believe Xfinity no longer does that.  Worst of all, you cannot speak to a human unless it is for a billing or technical issue.  Even then it takes forever to get to a person and half the time, they cannot help.  But lying is something I just cannot tolerate even though it seems to be the norm these days.  Why does Xfinity condone lying?  Or maybe they are encouraging it.  HMMMMM
