Terrible customer service. The owner rescheduled my jump time with no regard for the customer's schedule and for no disclosed reason, yet refused a refund. I was constantly awaiting a reply from my emails and couldn't get an answer when I called and they hadn't set up their voicemail for me to even leave a message. I'm disappointed in the unprofessional behavior to say the very least and I can't trust someone that unorganized with my safety.
