Poor service by Multi-choice Agents

I mistakenly paid a R1000 into a dstv account and after noticing that, I immediately asked for a refund on the 26/08/22 which was processed. But when I called on the 29th, I was told that my documents for refund are incomplete and have to resubmit a bank statement, ID copy and proof of payment, which I did on the same day. After that, I thought everything is in order, I only have to wait for 7 to 14 working days, as I was told. On the 6th of September, I decided to follow up on the process and that's when I was told that, their financial department declined my request due to insufficient documents. I then enquired as to which documents are outstanding? The agent I spoke to said, all documents are attached no need for additional documents, meaning my email on the 29th was sufficient for approval. To date, I'm still waiting and every time I call to ask, I get different stories with no way forward. Today, I called again and requested to speak to a manager - who promised that he will make sure everything is sorted and give me a call back before the end of business day to give an update, which he never did. At about 16h00, I made another call and the agent told me her manager had already left for the day. Now, I ask myself how long must one wait to get a refund, if you given a turn around time, that they don't honor themselves? I bet if it was my dstv account owing or in arrears, they would have blocked my account already. Now I regret ever having a dstv account because, you expected as a client to honor and pay your account on time but when it's their turn to pay you back, it takes forever . The level of unprofessionalism and dishonesty, is unacceptable and least expected from a big corporate like Multi-choice.
