I have been waiting for the reversed amount for 3 weeks now

Hi hello Peter I am Kegaogetswe Mokganya. I have asked Capitec to reverse money from a different account from a week before last. They reversed it bcos in that other person's account the money is no longer there to show that it has been reversed and everytime I ask what's going on they tell me they are still investigating. The money I asked them to reverse is R200 and I used my savings plan named business plan
