additional allow balance charged charges configuration contacted customer days decided dollars example grand item offer payment product remaining remove sale sell total trial

Using E-Junkie, can I sell my product (for example) through a $10 Trial Offer, then after 30 days it charges the remaining balance of $27. In the end, after 30 days the grand total sale would be 37 dollars. Does E-junkie allow for a trial offer configuration?
Also, If the customer decided the product was not for them before 30 days is up and contacted me to remove them from being charged the additional $27 dollars.... could I remove the customer via E-Junkie from being charged further?

I am sorry but E-junkie can only be used to sell an item for a one time payment.
