AIRLINK VIOLATION OF CONSUMER RIGHTS

I booked 2 flights in good faith with Airlink; Airlink then decided to change those flight times to something COMPLETELY different (not even close to the times I had originally booked) and, as such, I was forced to cancel and ask for a refund. Airlink is now sitting on this refund and holding on to my funds - profiting from this situation while i am unable to make alternative travel arrangements as i am out of pocket by 15600.88ZAR. This is a complete violation of my consumer rights and is totally *********. and I have sent COUNTLESS emails and called so many times - I keep getting shunted from one person to the other. This is appalling customer service - extremely disappointing and WRONG from Airlink.
