Vonage Cancelation Fees after 1 1/2 Years of POOR service!!!

Well, i just found out a dirty little secret about Vonage and their terms of service. If you were unlucky enough to sign up between February 1, 2007 and May 29, 2009 you agreed to a 2 YEAR contract. What are they thinking!!! Your not a cell phone company where you gave away a $250 phone for free, they made me BUY a router, and I am still locked into a 2 year contract, or pay a cancelation fee! I dont remember agreeing to a rate increase when i signed up, but they had no problems doing that. Now they are getting one last fee out of me before I drop there sorry butt.
