Pay back my money

On 16 March 2024 I erroneously paid R10 100. 00 into Multichoice bank account while attempting to pay a creditor. I immediately discovered my error and contacted Multichoice contact center. The agent asked me to send all relevant information and supporting documents. I did this. I was asked to further go to a walk-in center and produce same. I did this. I was told that my refund will be processed between 7 and 14 days. Today is 15 June 2024 and I have to date not received this money. I have called the call center from time to time. I am told that the refund is processed and will be paid into my bank account. I have explained to the call center agents the urgency of having this money paid back to me as this is a substantial amount in this economic time. I am indeed a subscriber to Multichoice and one would say that the money be used to pay my subscription, however my subscription is a mere R130.00 per month. I would like to call on anyone to please assist me with this issue. Thanks.
