Cancellations received 6-10 working days before the class date will receive a 50% refund (or be invoiced for 50% if payment hasn't yet been received). Cancellations received 5 days or less before the scheduled class date will receive no refund (or will be invoiced 100%). Each class we offer is subject to minimum attendance requirements, so we reserve the right to cancel a class due to insufficient enrollment. If we cancel a class, we will refund all enrollment fees or credit them toward the next scheduled class — your choice. iSi reserves the right to refuse enrollment based on competitor status, previous disruptive behavior, inability to pay or other.
