I joined this site for a trial, and couldn't log back on in order to view or cancel my membership. When I told them, I was sent a form to print and fill out, too see if maybe I would be able to get a refund. That was only after I filed a complaint with another site like this. Use this site only if you like giving away your money.
I was originally charged when I cancelled my membership, I wrote a message with my name and number, then called and refunded my full amount. I'm very happy with the outcome.
