CEMAIR *****ING MY MONEY!!

I have booked and paid for my plane ticket 01 November 2018 where after I was informed that the airline closed due to safety issues... It's now 5 months later and I STILL DID NOT GET MY MONEY BACK.. I have send countless emails and they have the same excuse everytime.. I'm fed up now and I want my MONEY NOW!!! I WILL SUE THE AIRLINE FOR THEFT AND I will NOT WAIT OR EXCEPT ANOTHER EXCUSE any longer. I want my money back NOW! R1700 is not small change and it's my money for no service rendered.
