Refund for plane ticket not yet received

I have booked a plane ticket with my credit card on Skywise Airline. I received a message saying the transaction did not go through, I should try again. After the second time I received the same message. I checked my emails and received two confirmation messages of two airline tickets booked just a few minutes apart with a reference number for each. The amount of R 1797 went of twice from my account.<br> <br> I immediately emailed the company (24 Feb)and explained what happened. The next day I also phoned Skywise and spoke to Mamela. She told me to send my bank statement for the refund. I sent it the same afternoon. I received confirmation that she had received it.<br> <br> On the 2nd of March I emailed again and received a reply on 4 March saying they are still processing it. The same day Mr David Mouton apologised for the delay and explained the process. I emailed again on 9,10,16 and 20 March. The reply was that Nedbank insists on a 21 day holding period, which was causing the delay.<br> <br> The 3rd of April emailed again (11 days after the supposed 21 day holding period). Today is 33 days later (counting only working days) and I still have not yet received any refund.<br>
