Refund

I would like to complain about Skywise' bad service and ignorance. I booked a ticket from CPT to JNB for the 1st of October returning on the 11th of October for 2 minors. The agent who was assisting me booked it the other way around and I was overcharged as the routing was done wrong, I went to advise them about the mistake and I was assisted by a different agent who managed to correct the routings but omitted to book the children as minors. They were supposed to refund me the difference, which is R1446.82. The minors were charged R150 each at the airport in CPT so that they could be assisted as Specials of which it was included in the original booking. I sent an email complaining about the amount that they charged the minors in CPT as they were not supposed to be charged cause i originally booked them as minors(Specials) and no one responded till today. I never received the initial refund of R1446.82 plus the R300, which I was promised that it will be done within 21 days, the 21 days was long over due on the 21st of October and still no communication from Skywise. I am not happy, I am stressed and frustrated by this ordeal, I am disgusted by the way they are handling this matter.
