Tickets refund

I booked return tickets from Bloem to Durban and back for the Easter weekend. I then got a job in Pretoria that I started in early April. Needless to say I had to cancel my tickets. This was done on the 2nd of April and the lady I spoke to when cancelling told me it would take two weeks to get my refund. Two weeks pass and when I got no refund I called the number for enquiry and a guy proceeded to tell me that the woman made a mistake, reversal of transactions takes four weeks. I then sent an email to customer care for which I received no response, and then sent one to info who informed me that they had only processed the reversal on the 20th of April and it should be in my bank account on Monday the 25th of April. Monday came and went and nothing came in. Had to make three more follow up calls and send various emails following up, only for them to say that they don't have my banking details. I then provided said details in an email and asked when I would be getting my money to which I received no answer. It's May now and I still haven't received my money from them and the guy that is apparently in charge of the refunds is unavailable.
