Frustrated and angry

On Wednesday (20/08/2025) i paid my Rain account via the Capitec App. The payment went off twice, my monthly payment is R625.00, which means i paid R1250.00. I send a message via Rain chatbot which they did confirm that they can see the double payment and i asked for a reversal and they said that someone from their support will contact me. I did receive a call within a few minutes; however, the call disconnected before i could speak to anyone. I sent another message asking them to call me for a reversal. Every time i make follow up i get a generated message saying someone will call me, but no one has called me. I want my money reversed back into my account ASAP.
