Very very poor service from ABSA

I have lodged a complaint with ABSA dispute division on 15 October 2022 to reverse a transaction that I have made on my credit card for fligth tickets after part of the flight was cancelled the following day. I have received 6 different reference numbers and a request from ABSA to afford them a period of 30 days to investigate the matter. I only received feedback from ABSA after contacting the complaints division enquiring an update. On 15 November 2022 I have received an email from ABSA indicating that a refund would be made into my account after 72 hours. After dispatching various emails to ABSA again I have not received the refund to date.
