They will bill you monthly even if you don't authorize them sign up for the service. (BTWI'm a lawyer.) When my credit card continued to show bills, I contacted them to cancel and they said they had no record of my account or credit card. It required 2 additional calls and a conference call with my credit card company to cancel service because they were working off old credit card number. In the meantime, I was billed continuously for months. NIGHTMARE.
