Failure to pay refund: Its been a year now

I bought a flight ticket for R3646.90 to Namibia however the trip was postponed I therefore called Computicket and they informed me that in order to change the date I have to pay an additional R6264.41 in order to change the date. I made the payment of R6264.41 on the 14 March 2019.

Unfortunately during this period my mother passed away on the 13 April 2019 I than had to cancel my trip. I contacted the office and they told me I will be refunded between 6-8 weeks. Which up until now 03 December 2020 I have not received.

The refund reference number is T1901GB1S85Y. The Computicket Travel office sent me an email on the 17 April 2019 to confirm that they have received my email and communication and have approved my refund. But have not paid my money so far.

The people at Computickets that I have communicated with so far is 1. ***(who acknowledged my refund email and stated that my refund will be repaid.

2. Computicket retail support *** (No assistance was given. I was told to go to the Waterfront office however the office is closed here in Cape Town
