How do I cancel my subscription and get a refund?

There's no early termination fee for cancelling  the costlier month-to-month plan.  You can cancel a month-to-month anytime without penalty.

But there is a fee for cancelling an annual plan (paid monthly, or prepaid).   The cancellation fee is 50% of your remaining months of service.  To avoid penalty fees, wait until your 12th month of service to cancel, before it auto renews for another year.

When you go past the allowed 14 days you have agreed to a one year contract, which has a fee of 1/2 of the remaining time if you cancel before the end of your contract year... ask support
