Refund Query not attended

I booked a flight online from Cape Town to Johannesburg on 06/06/2015 and funds were not cleared by my bank. Obviously, I was not allowed to board the plane and was asked to do another payment of which I did. Even that flight was cancelled for the next day. Later on the week, the first payment went through, meaning I have paid twice for a single flight. I have been trying to get a refund since then and has taken almost 2 months without any success. This is the most disgusting service I have ever recieved from any service provider and I vouch not to take this airline again. You might save on flight prices but the time you spend on the phone for queries to be addressed is not worth the experience. Deal with proper and reputable airlines....
