45 Days later and still no Refund

On the 11th June 2015 between 7 & 8pm I made a booking from Durban to OR Tambo airport. My online booking was successful and I chose to make a SID payment instead of using a credit card. Needless to say my SID payment was successful (I even cleared the funds as it was a different bank). I printed the confirmation of payment and phoned the call center after 15 minutes as it was not taking me back to Mango's webpage once the payment was made. Their response if the payment went through I should go to the airport tomorrow and show them my confirmation of payment however they cannot guarantee me a flight unless I book again. After numerous calls on Friday 12th June I decided to book with Kulula as I needed to get to the funeral urgently and I was reassured by the call center agents I would get my money back once a claim was submitted. It is now 45 days later - no refund has been received we have comp**** by giving them all the necessary documents. We have sent emails and made phone calls and still no luck. When my husband called yesterday they said they would call him back with answers. Well you can guess, still no answers or money!!!!!!
