Complaint Against Oribi Gorge

I sustained a concussion at Oribi Gorge while ziplining. The injury was due to the gross negligence of the instructors in not telling us how to break and also instructing me to proceed while there was another person on the zip line.

An incident report was filed by one of the staff and I was told I'd be refunded and reimbursed for the medical expenses I've incurred. This happened on the 2nd Jan and its been two months now with no recourse. I keep getting the run-around from the receptionist and the manager isn't responding to my emails.
