Shameful service and not keeping to your word. Not satisfied

On 28 Sep 2023, I reported 2 *****ulent transactions on my discovery card. They were 2 separate charges for the same merchant. A few days later, they refunded the 1, but not the other. So on 6 Nov 2023, I called in to report this, and I was told that it was an error and that I'd be refunded for the second one too that same day. I am still waiting. I also asked that a manager calls me and I haven't heard from anyone since. What shameful service!
