Absa's service is pathetic

Have been trying for the past 2 months to close my Absa credit card. Absa has to refund me R550 before the card account can be closed and that they find impossible to do. Several calls and e-mails later the account is still active and I've given up. Phoned the call center again on 6 April 2021 and a consultant promised to speak to her supervisor and call me back. I haven't received any feedback. I called again today and was eventually requested to visit a branch which I refuse to do again. Will never do business with Absa again.
