Med aid REFUND humdinger

I regret this mistakenly made payment to a wrong med aid account that I no longer a member from my bank app on the 25 October 2023 offsetting my budget for the month hugely inconveniencing. To be honest don't know where my head was at, apparently still had this mediad on my beneficiary list used to pay them manually and I simply press pay and my money was gone. I didn't expect it will be this long drawn out process to extract my money back 03 November 2023 was told instruction to pay has been forwarded to finance it will take approximately 5 working days. I mean since the 25 October 2023 the day I made the mistaken payment I immediately lodged a refund request with my bank and with all the technology involved that I believe should be at the disposal of the med aid in question I did not expect that it will be this hard that even to date I still have not been refunded.
