Comcast xfinity A Rip Off Monopoly! $188 a month for INTERNET??? Internet, Internet

I signed up for comcast internet a few years ago.  It was supposed to be a special price of $19.99 but it was 45 bucks.  The first red flag, but what can you do?  There are no other options for high speed internet.  (there is a DSL plan around, but it's about the same price as comcast and about as "fast" as dial up.)

Then about two years ago I signed up for a $24.99 a month special to ad a TV package.   It turned out the $24.99 package is actually $40 so my bill should have been $85 a month.  And it was- for ONE month.

Then the bill steadily increased every month, even though I had only basic cable and internet and no movie channels, etc.  We didn't watch any extra Pay per view or anything else.  Mostly just the History Channel. 

May 2011- $125
June 2011- $127
July 2011- $138
August 2011- $148
Sept 2011- $149
Oct 2011- 150
Nov 2011- 151

So by now I'm completely fed up and cancelled before I could be billed for December.  I took back the equipment and everything. So guess what my bill is this month- internet only, no TV at all?

$186.56

Our initial contract was fulfilled years ago so there isn't a cancellation fee. 

This is SUCH a rip off!  They shouldn't be able to have a complete monopoly and set the price with no competition allowed.
