Billing error

I got a subscriber today. C2 shows the next Charge date is Aug 7th. How could it be? My system has trial period of 7 days, not a month.

Your Subscriber Report shows that your subscriber was charged on July 7 and will be charged again 30 days later. There is nothing wrong with this, since you yourself specified a monthly billing cycle.

Sorry, my bad. I did not understand how trial period works. If a person subscribe for trial period and unsub right before trial period ends. Can he/she repeatedly do this without charge?
