Internet and Tech support

I just want Xfinity to know something.  It's not ok to bump up my speed and then charge me double.  It's not ok that when I go online to change my plan it doesn't let me do it.  It's not ok that when I get on chat, an hour later I'm still there with no resolution.  Then when I get on the phone with somebody, they tell me my modem that I own, doesn't support lower speeds.  That's total [Edited: "Language"].  I signed up for 300mb which is PLENTY for me.  Now to switch back to that plan I have to rent your modem?  Let me tell you something......I just got done signing up with GoNetspeed.  Their website is light years ahead of Xfinity.  Everything works as it should.  When I call them with a question, a person answers the phone, not a stupid bot.  I wasn't online for an hour trying to get to a person.  These people even called me back to ask if they had answered all my questions.  Now I will have a BETTER internet connection, with speeds up and down the same, for LESS money than Xfinity is charging me now.  I didn't want to bother having to get a new line put in my house.  I would be happy to stay with Xfinity, if you just let me go back to my old 300mb plan.  I'm out of work right now and can't afford to have my bill double.  So, since you want to be GREEDY, I'll just go with somebody else.  Nuff said.
