Very Bad service.

I was contacted by a lady from Daly Credit Corporation on the 20th of May 2021, stating that I will receive a 80% settlement on my ABSA Credit card, if I will pay R611 for 3 months, if I miss one payment, the discount will fall away. I've made payments on the 25th of May, 25th of June and 25th of July 2021. On the 25th of August my account was debited once again. Since then I am struggling to receive a refund. If you phone them, they simply reply with, when they have feedback they will phone you, and nobody returns the calls, not even a manager.
