I paid for a year of service - $300 - and created only one contract. Not a great value, but it's what I signed up for. However, they auto-billed me for a second year and did not answer the phone when I tried to cancel the service. They refused to help me over email (said I had to call their CS line).
I called my credit card company and had the charge reversed, but being that Rocketlawyer is, after all, run by lawyers - they got the charge re-instated claiming that having printed one contract I was liable for paying the 2nd year.
Took months to finally resolve, but they did not refund all of my money. I would never use this service again.
