Demandforce Unethical Internet

The sales rep from this company told me I could cancel with 30 day notice if the service wasn't working.  It only generated 1 review in 6 months.  We I called in to cancel, I was told I would be billed for the entire contract.  When I finally talked to a "manager" 1 week later, he wouldn't address the salesperson's lie and would not consider allowing me to cancel.  He said "there is no one else to talk to" when I asked to speak to his supervisor.  Basically, they lie to get you to sign up and then produce no results.  They are rude.  Recently, they were aquired by INTUIT and I am suprised that they allow them to continue operating this way.
