Horrific experience

I booked a one-way flight at the cost of R595.00 on the 28/9/2015 via Credit Card, online. After not receiving my booking reference, I emailed Skywise asking why I have not yet received it. I was unsuccessful in my attempt & received an email 2 weeks later, stating that they cancelled my booking due to payment not reflecting on time although I immediately got an SMS from ABSA. They told me that they will give me a refund on my ticket but I had to pay extra if I was to book again. It has been 3 weeks & I have not yet received my refund after calling & emailing millions of different occasions. I need the money back ASAP. This is *****ing & I am terribly unhappy. They have stopped replying to my emails. It is pathetic.
