Im angry and need my money!

I was assisted by Nqobile to make a cancelation and refund, she apparently did not write the right date, this is in the middle of April, I then called in last Wed and spoke to Lindo, who said he would speak to his supervisor and get back to me in an hour... 4 hrs later I sent a whatsapp chat to be called back and Sibongile called me back, I explained everything then she put me on hold for Lindo to speak to me, Lindo apologized and said he has not received feedback from his manager and will call me back, wen he did call me back, he said they have escalated the matter and I will be paid within the latest 72hrs. Today, 11 May2026, I call in and speak to Sibongile who says she will speak to the refunds/accounts department and get back to me, I tell her I want my money and im giving her an hr to get info a just give me SOME feedback... im going on two hrs now!! When they are selling their products to us, the respond quickly, but once we become their clients then they give us days on end!! Im very angry, I need that money... its a shortfall that I was not supposed to experience!! What should I do?
