Kulula refund

On the 14th of June 2019 i incorrectly booked a ticket for 2 people from Johannesburg to capetown instead of capetown to Johannesburg. When i realised i made the mistake i called the call centre to cancel however it was after hours and i could not be assisted. I then booked the correct ticket using Kulula still. On the 15th of June 2019 i then called the kulula call centre to inform them of the error. I was then asked to send both the incorrect ticket as well as the correct ticket which i subsequently booked. I was then informed that a refund will be instituted and it will take about 4 to 6 weeks before i coud get it. 6 weeks came and passed and there was no refund. In September/ October 2019 i started following up. I was then informed that no refund was requested. The person assisting me then informed me that the matter will be investigated and i will be informed of the outcome. 29 October 2019 i sent a follow up email requesting feedback and till today i have not received a response. I am really disappointed at the pace in which this matter is being looked at.
