Card dispute - Capitec not resolving the issue!

I went for dinner, tried to pay with my card, it got declined twice, although there was definitely money available. I ended up paying with a card from another bank. Later that evening, the money does go off my Capitec account as well. Checked with the restaurant, it didn't go off twice on their side. I got a letter from them confirming this. I raised the issue with card disputes, they are yet to get back to me (more than a month later). And when I called today, I got told that they did reply to me? I haven't received any feedback, and more important I also didn't get my money refunded. And to add insult to injury, they asked me if I will pay the R80 fee to pay me back, should they decide to pay me back! When I started asking difficult questions, and not just accepting the half baked answer, I got put on hold, and the call centre agent never got back to me, was on hold for more than 27 minutes. Issue still not resolved
